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.

Fixes an issue where access rules failed to validate:

    Cannot validate request with restricted access rules. Set
    service_type in [keystone_authtoken] to allow access rule validation

I've used the values from the endpoint. This was mostly a straight
forward copy and paste, except:

- versioned endpoints e.g cinderv3 where I stripped the version
- monasca has multiple endpoints associated with a single service. For
  this, I concatenated logging and monitoring to be logging-monitoring.

In services which use the Apache HTTP server to service HTTP requests,
there exists a TimeOut directive [1] which defaults to 60 seconds. APIs
which come under heavy load, such as Cinder, can sometimes exceed this
which results in a HTTP 504 Gateway timeout, or similar. However, the
request can still be serviced without error. For example, if Nova calls
the Cinder API to detach a volume, and this operation takes longer
than the shortest of the two timeouts, Nova will emit a stack trace
with a 504 Gateway timeout. At some time later, the request to detach
the volume will succeed. The Nova and Cinder DBs then become
out-of-sync with each other, and frequently DB surgery is required.

Although strictly this category of bugs should be fixed in OpenStack
services, it is not realistic to expect this to happen in the short
term. Therefore, this change makes it easier to set the Apache HTTP
timeout via a new variable.

An example of a related bug is here:

https://bugs.launchpad.net/nova/+bug/1888665

Whilst this timeout can currently be set by overriding the WSGI
config for individual services, this change makes it much easier.

When the internal VIP is moved in the event of a failure of the active
controller, OpenStack services can become unresponsive as they try to
talk with MariaDB using connections from the SQLAlchemy pool.

It has been argued that OpenStack doesn't really need to use connection
pooling with MariaDB [1]. This commit reduces the use of connection
pooling via two configuration options:

- max_pool_size is set to 1 to allow only a single connection in the
  pool (it is not possible to disable connection pooling entirely via
  oslo.db, and max_pool_size = 0 means unlimited pool size)
- lower connection_recycle_time from the default of one hour to 10
  seconds, which means the single connection in the pool will be
  recreated regularly

These settings have shown better reactivity of the system in the event
of a failover.

It was found to be useless in [1].

It is one of distro_python_version usages.

Note Freezer and Horizon still use python_path (and hence
distro_python_version) for different purposes.

Introduce kolla_address filter.
Introduce put_address_in_context filter.

Add AF config to vars.

Address contexts:
- raw (default): <ADDR>
- memcache: inet6:[<ADDR>]
- url: [<ADDR>]

Other changes:

globals.yml - mention just IP in comment

prechecks/port_checks (api_intf) - kolla_address handles validation

3x interface conditional (swift configs: replication/storage)

2x interface variable definition with hostname
(haproxy listens; api intf)

1x interface variable definition with hostname with bifrost exclusion
(baremetal pre-install /etc/hosts; api intf)

neutron's ml2 'overlay_ip_version' set to 6 for IPv6 on tunnel network

Remove neutron-server ml2_type_vxlan/vxlan_group setting
as it is not used (let's avoid any confusion)
and could break setups without proper multicast routing
if it started working (also IPv4-only)

haproxy upgrade checks for slaves based on ipv6 addresses

TODO:

ovs-dpdk grabs ipv4 network address (w/ prefix len / submask)
not supported, invalid by default because neutron_external has no address
No idea whether ovs-dpdk works at all atm.

ml2 for xenapi
Xen is not supported too well.
This would require working with XenAPI facts.

rp_filter setting
This would require meddling with ip6tables (there is no sysctl param).
By default nothing is dropped.
Unlikely we really need it.

ironic dnsmasq is configured IPv4-only
dnsmasq needs DHCPv6 options and testing in vivo.

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.
See: https://github.com/ansible/ansible/issues/63227

Bifrost Train does not support IPv6 deployments.
