Allow operators to use custom parameters with the ceilometer-upgrade
command. This is quite useful when using the dynamic pollster subsystem;
that sub-system provides flexibility to create and edit pollsters configs,
which affects gnocchi resource-type configurations. However, Ceilometer
uses default and hard-coded resource-type configurations; if one customizes
some of its default resource-types, he/she can get into trouble during
upgrades. Therefore, the only way to work around it is to use the
"--skip-gnocchi-resource-types" flag. This PR introduces a method for
operators to execute such customization, and many others if needed.

In kolla ansible we typically configure services to communicate via IP
addresses rather than hostnames. One accidental exception to this was
live migration, which used the hostname of the destination even when
not required (i.e. TLS not being used for libvirt).

To make such hostnames work, k-a adds entries to /etc/hosts in the
bootstrap-servers command. Alternatively users may provide DNS.

One problem with using /etc/hosts is that, if a new compute host is
added to the cloud, or an IP address is changed, that will not be
reflected in the /etc/hosts file of other hosts. This would cause live
migration to the new host from an old host to fail, as the name cannot
be resolved.

The workaround for this was to update the /etc/hosts file (perhaps via
bootstrap-servers) on all hosts after adding new compute hosts. Then the
nova_libvirt container had to be restarted to pick up the change.

Similarly, if user has overridden the migration_interface, the used
hostname could point to a wrong address on which libvirt would not
listen.

This change adds the live_migration_inbound_addr option to nova.conf. If
TLS is not in use for libvirt, this will be set to the IP address of the
host on the migration network. If TLS is enabled for libvirt,
live_migration_inbound_addr will be set to migration_hostname, since
certificates will typically reference the hostname rather than the
host's IP. With libvirt TLS enabled, DNS is recommended to avoid the
/etc/hosts issue which is likely the case in production deployments.

Elasticsearch 6.x dropped support for mapping types[1], which by default
the Kibana index used. This means that when deploying ELK 6.x, the
Kibana index must be migrated to the new schema to preserve dashboards
and visualizations. There is a process defined[2], which involves
creating a new index with the specified schema, then reindexing the old
index's data into the new index, then doing a rename/delete.

This adds support for that workflow via Ansible. It takes place after
the ES container is restarted after an upgrade, so there will be a
(short) period of time where the Kibana index is not migrated. During
this time, Kibana still loads, but presents the user with a status
screen informing that the index needs migration.

Currently there are a few services that perform host configuration
tasks. This is done in config.yml. This means that these changes are
performed during 'kolla-ansible genconfig', when we might expect not to
be making any changes to the remote system.

This change separates out these host configuration tasks into a
config-host.yml file, which is included directly from deploy.yml.

One change in behaviour is that this prevents these tasks from running
during an upgrade or genconfig. This is probably what we want, but we
should be careful when any of these host configuration tasks are
changed, to ensure they are applied during an upgrade if necessary.

One way to improve the performance of Ansible is through fact caching.
Rather than gather facts in every play, we can configure Ansible to
cache them in a persistent store. An example Ansible configuration for
doing this is as follows:

[defaults]
gathering = smart
fact_caching = jsonfile
fact_caching_connection = ./facts
fact_caching_timeout = 86400

This does not affect Kolla Ansible however, since we use the setup
module which unconditionally gathers facts regardless of the state of
the cache. This gets worse with large inventories limited to a small
batch of hosts via --limit or serial, since the limited hosts must
gather facts for all others.

One way to detect whether facts exist for a host is via the
'module_setup' variable, which exists only when facts exist. This change
uses the 'module_setup' fact to determine whether facts need to be
gathered for hosts outside of the batch. For hosts in the batch, we
switch from using the setup module to gather_facts on the play, which
can use the 'smart' gathering logic.

Deploy HAProxy on one or more servers. Add another server to the
inventory in the haproxy group, and run the following:

kolla-ansible prechecks --limit <new host>

The following task will fail:

    TASK [haproxy : Checking if kolla_internal_vip_address and
    kolla_external_vip_address are not pingable from any node]

This happens because ansible does not execute on hosts where
haproxy/keepalived is running, and therefore does not know that the VIP
should be active.

This change skips VIP prechecks when not all HAProxy hosts are in the
play.

The 'kolla-ansible stop' command can be used to stop the services
running on hosts. However, if you run this command in an environment
with heterogeneous nodes (most real world scenarios have at least
control/compute), then it fails. This is because it only checks
whether a container is enabled, and not whether the host is in the
correct group. For example, it fails with nova-libvirt:

    No such container: nova_libvirt to stop.

This change fixes the issue by only attempting to stop containers on
hosts to which they are mapped.
