Render {{ openstack_service_workers }} for workers
of each openstack service is not enough. There are
several services which has to have more workers because
there are more requests sent to them.

This patch is just adding default value for workers for
each service and sets {{ openstack_service_workers }} as
default, so value can be overrided in hostvars per server.
Nothing changed for normal user.

The bootloader used to boot Ironic nodes in UEFI boot mode during

snponly.efi. This is in line with the default UEFI iPXE bootloader used

The admin interface for endpoints never had any real use, the

Basically, there are three main installation scenario:

Scenario 1:
Ironic installation together with other openstack services
including keystone. In this case variable enable_keystone
is set to true and keystone service will be installed
together with ironic installation. It is possible realise this
scenario, no fix needed

Scenario 2:
Ironic installation with connection to already installed
keystone. In this scenario we have to set enable_keystone
to “No” to prevent from new keystone service installation
during the ironic installation process. But in other hand,
we need to have correct sections in ironic.conf to provide
all information needed to connect to existing keystone.
But all sections for keystone are added to ironic.conf only
if enable_keystone var is set to “Yes”. It isn’t possible
to realise this scenario. Proposed fix provide support for
this scenario, where multiple regions share the same
keystone service.

Scenario 3:
No keystone integration. Ironic don't connect to Keystone.
It is possible realise this scenario, no fix needed

Proposed solution also keep the default behaviour: if no
enable_keystone_integration is manually defined by default
it takes value of enable_keystone variable and all behaviour
is the same. But if we don't want to install keystone and
want to connect to existing one at the same time, it will be
possible to set enable_keystone var to “No”
(preventing keystone from installation) and at the same
time set ironic_enable_keystone_integration to Yes to allow
needed section appear in ironic.conf through templating.

In the Xena release, Ironic removed the iSCSI driver [1]. The
recommended driver is direct, which uses HTTP to transfer the disk
image. This requires an HTTP server, and the simplest option is to use
the one currently deployed when enable_ironic_ipxe is set to true. For
this reason, this patch always enables the HTTP server running on the
conductor.

iPXE is still enabled separately, since it cannot currently be used at
the same time as PXE.

By default, Ansible injects a variable for every fact, prefixed with
ansible_. This can result in a large number of variables for each host,
which at scale can incur a performance penalty. Ansible provides a
configuration option [0] that can be set to False to prevent this
injection of facts. In this case, facts should be referenced via
ansible_facts.<fact>.

This change updates all references to Ansible facts within Kolla Ansible
from using individual fact variables to using the items in the
ansible_facts dictionary. This allows users to disable fact variable
injection in their Ansible configuration, which may provide some
performance improvement.

This change disables fact variable injection in the ansible
configuration used in CI, to catch any attempts to use the injected
variables.

The goal for this push request is to normalize the construction and use
 of internal, external, and admin URLs. While extending Kolla-ansible
 to enable a more flexible method to manage external URLs, we noticed
 that the same URL was constructed multiple times in different parts
 of the code. This can make it difficult for people that want to work
 with these URLs and create inconsistencies in a large code base with
 time. Therefore, we are proposing here the use of
 "single Kolla-ansible variable" per endpoint URL, which facilitates
 for people that are interested in overriding/extending these URLs.

As an example, we extended Kolla-ansible to facilitate the "override"
of public (external) URLs with the following standard
"<component/serviceName>.<companyBaseUrl>".
Therefore, the "NAT/redirect" in the SSL termination system (HAproxy,
HTTPD or some other) is done via the service name, and not by the port.
This allows operators to easily and automatically create more friendly
 URL names. To develop this feature, we first applied this patch that
 we are sending now to the community. We did that to reduce the surface
  of changes in Kolla-ansible.

Another example is the integration of Kolla-ansible and Consul, which
we also implemented internally, and also requires URLs changes.
Therefore, this PR is essential to reduce code duplicity, and to
facility users/developers to work/customize the services URLs.

Previously we mounted /etc/timezone if the kolla_base_distro is debian
or ubuntu. This would fail prechecks if debian or ubuntu images were
deployed on CentOS. While this is not a supported combination, for
correctness we should fix the condition to reference the host OS rather
than the container OS, since that is where the /etc/timezone file is
located.

For the CentOS 7 to 8 transition, we will have a period where both
CentOS 7 and 8 images are available. We differentiate these images via a
tag - the CentOS 8 images will have a tag of train-centos8 (or
master-centos8 temporarily).

To achieve this, and maintain backwards compatibility for the
openstack_release variable, we introduce a new 'openstack_tag' variable.
This variable is based on openstack_release, but has a suffix of
'openstack_tag_suffix', which is empty except on CentOS 8 where it has a
value of '-centos8'.

Ironic provides a feature to allow instance images to be served from a
local HTTP server [1]. This is the same server used for PXE images with
iPXE. This does not work currently because the ironic_ipxe container
does not have access to /var/lib/ironic/images (ironic docker volume),
where the images are cached. Note that to make use of this feature, the
following is required in ironic.conf:

[agent]
image_download_source = http

the ironic volume.

KNOWN ISSUES (beyond us):

One cannot use IPv6 address to reference the image for docker like we
currently do, see: https://github.com/moby/moby/issues/39033
(docker_registry; docker API 400 - invalid reference format)
workaround: use hostname/FQDN

RabbitMQ may fail to bind to IPv6 if hostname resolves also to IPv4.
This is due to old RabbitMQ versions available in images.
IPv4 is preferred by default and may fail in the IPv6-only scenario.
This should be no problem in real life as IPv6-only is indeed IPv6-only.
Also, when new RabbitMQ (3.7.16/3.8+) makes it into images, this will
no longer be relevant as we supply all the necessary config.
See: https://github.com/rabbitmq/rabbitmq-server/pull/1982

For reliable runs, at least Ansible 2.8 is required (2.8.5 confirmed
to work well). Older Ansible versions are known to miss IPv6 addresses
in interface facts. This may affect redeploys, reconfigures and
upgrades which run after VIP address is assigned.

After all of the discussions we had on
"https://review.opendev.org/#/c/670626/2", I studied all projects that
have an "oslo_messaging" section. Afterwards, I applied the same method
that is already used in "oslo_messaging" section in Nova, Cinder, and
others. This guarantees that we have a consistent method to
enable/disable notifications across projects based on components (e.g.
Ceilometer) being enabled or disabled. Here follows the list of
components, and the respective changes I did.

* Aodh:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.

* Congress:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.

* Cinder:
It was already properly configured.

* Octavia:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.

* Heat:
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components

* Ceilometer:
Ceilometer publishes some messages in the rabbitMQ. However, the
default driver is "messagingv2", and not ''(empty) as defined in Oslo;
these configurations are defined in ceilometer/publisher/messaging.py.
Therefore, we do not need to do anything for the
"oslo_messaging_notifications" section in Ceilometer

* Tacker:
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components

* Neutron:
It was already properly configured.

* Nova
It was already properly configured. However, we found another issue
with its configuration. Kolla-ansible does not configure nova
notifications as it should. If 'searchlight' is not installed (enabled)
the 'notification_format' should be 'unversioned'. The default is
'both'; so nova will send a notification to the queue
versioned_notifications; but that queue has no consumer when
'searchlight' is disabled. In our case, the queue got 511k messages.
The huge amount of "stuck" messages made the Rabbitmq cluster
unstable.

* Watcher

* Barbican
I created a mechanism similar to what we have in Cinder, Nova,
and others. I also added a configuration to 'keystone_notifications'
section. Barbican needs its own queue to capture events from Keystone.
Otherwise, it has an impact on Ceilometer and other systems that are
connected to the "notifications" default queue.

* Keystone
Keystone is the system that triggered this work with the discussions
that followed on https://review.opendev.org/#/c/670626/2

. After a long
discussion, we agreed to apply the same approach that we have in Nova,
Cinder and other systems in Keystone. That is what we did. Moreover, we
introduce a new topic "barbican_notifications" when barbican is
enabled. We also removed the "variable" enable_cadf_notifications, as
it is obsolete, and the default in Keystone is CADF.

* Mistral:
It was hardcoded "noop" as the driver. However, that does not seem a
good practice. Instead, I applied the same standard of using the driver
and pushing to "notifications" queue if Ceilometer is enabled.

* Cyborg:
I created a mechanism similar to what we have in AODH, Cinder, Nova,
and others.

* Murano
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components

With Docker CE, the daemon sets the default policy of the iptables
FORWARD chain to DROP. This causes problems for provisioning bare metal
servers when ironic inspector is used with the 'iptables' PXE filter.
It's not entirely clear why these two things interact in this way,
but switching to the 'dnsmasq' filter works around the issue, and is
probably a good move anyway because it is more efficient.

We have added a migration task here to flush and remove the ironic-inspector
iptables chain since inspector does not do this itself currently.

This allows ironic service endpoints to use custom hostnames, and adds the
following variables:

* ironic_internal_fqdn
* ironic_external_fqdn
* ironic_inspector_internal_fqdn
* ironic_inspector_external_fqdn

These default to the old values of kolla_internal_fqdn or
kolla_external_fqdn.

This also adds ironic_api_listen_port and ironic_inspector_listen_port
options, which default to ironic_api_port and ironic_inspector_port for
backward compatibility.

These options allow the user to differentiate between the port the
service listens on, and the port the service is reachable on. This is
useful for external load balancers which live on the same host as the
service itself.

well as inspection if Neutron is disabled.

The dnsmasq PXE filter [1] provides far better scalability than the
iptables filter typically used. Inspector manages files in a dhcp-hostsdir
directory that is watched by dnsmasq via inotify. Dnsmasq then either
whitelists or blacklists MAC addresses based on the contents of these
files.

This change adds a new variable, ironic_inspector_pxe_filter, that can
be used to configure the PXE filter for ironic inspector. Currently
supported values are 'iptables' and 'dnsmasq', with 'iptables' being the
default for backwards compatibility.

Having all services in one giant haproxy file makes altering
configuration for a service both painful and dangerous. Each service
should be configured with a simple set of variables and rendered with a
single unified template.

Available are two new templates:

* haproxy_single_service_listen.cfg.j2: close to the original style, but
only one service per file
* haproxy_single_service_split.cfg.j2: using the newer haproxy syntax
for separated frontend and backend

For now the default will be the single listen block, for ease of
transition.
