Fixed Grafana role tasks failing when running
with Ansible check mode enabled.

(cherry picked from commit b59fe6cc)

Refactor that prepares kolla_container_facts
module for introducing more actions that will be moved
from kolla_container module and kolla_container_volume_facts.

This change is based on a discussion about adding a new action
to kolla_container module that retrieves all names of the running
containers. It was agreed that kolla-ansible should follow Ansible's
direction of splitting modules between action modules and facts
modules. Because of this, kolla_container_facts needs to be able
to handle different requests for data about containers or volumes.

The Kolla project supports building images with
user-defined prefixes. However, Kolla-ansible is unable
to use those images for installation.

This patch fixes that issue.

Most roles are not leveraging the jinja filters available.
According to [1] filtering the list of services makes the execution
faster than skipping the tasks.

This patchset also includes some cosmetic changes to genconfig.
Individual services are now also using a jinja filter. This has
no impact on performance, just makes the tasks look cleaner.

Naming of some vars in genconfig was changed to "service" to make
the tasks more uniform as some were previously using
the service name and some were using "service".

Three metrics from the deployment were taken and those were
- overall deployment time [s]
- time spent on the specific role [s]
- CPU usage (measured with perf) [-]
Overall genconfig time went down on avg. from 209s to 195s
Time spent on the loadbalancer role went down on avg. from 27s to 23s
Time spent on the neutron role went down on avg from 102s to 95s
Time spent on the nova-cell role went down on avg. from 54s to 52s
Also the average CPUs utilized reported by perf went down
from 3.31 to 3.15.
For details of how this was measured see the comments in gerrit.

Task `Check if extra configuration file exists` picks up all files in
`{{ node_custom_config }}/grafana` including those that get handled
specially later on.
While `prometheus.yml` and `provisioning.yml` are best excluded from
extra config , because their treatment requires more than just copying,
`grafana_home_dashboard.json` may simply be treated as extra config,
which saves the execution of two additional tasks.

Fixes not being able to add additional plugins at build time due to the
`grafana` volume being mounted over the existing `/var/lib/grafana`
directory. This is fixed by copying the dashboards into the container
from an existing bind mount instead of using the ``grafana`` volume.
This however leaves behind the volume which should be removed with
`docker volume rm grafana` or by setting `grafana_remove_old_volume` to
`True`.

When running in check mode, some prechecks previously failed because
they use the command module which is silently not run in check mode.
Other prechecks were not running correctly in check mode due to e.g.
looking for a string in empty command output or not querying which
containers are running.

This change fixes these issues.

Regularly, we experience issues in Kolla Ansible deployments because we
use wrong options in OpenStack configuration files. This is because
OpenStack services ignore unknown options. We also need to keep on top
of deprecated options that may be removed in the future. Integrating
oslo-config-validator into Kolla Ansible will greatly help.

Adds a shared role to run oslo-config-validator on each service. Takes
into account that services have multiple containers, and these may also
use multiple config files. Service roles are extended to use this shared
role. Executed with the new command ``kolla-ansible validate-config``.

Kolla Ansible is switching to OpenSearch and is dropping support for
deploying ElasticSearch. This is because the final OSS release of
ElasticSearch has exceeded its end of life.

Monasca is affected because it uses both Logstash and ElasticSearch.
Whilst it may continue to work with OpenSearch, Logstash remains an
issue.

In the absence of any renewed interest in the project, we remove
support for deploying it. This helps to reduce the complexity
of log processing configuration in Kolla Ansible, freeing up
development time.

Grafana requires the scrape interval to be set to be able to compute
$__rate_interval. The default is 15s which does not match the kolla
default of 60s. The symptom of not setting this is that you will see
"no data" when zooming graphs that use rate queries. This occurs as the
interval will be set to a period shorter than the scrape interval.
The recommendation is that you use a common scrape interval for all
jobs. See:

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 current behaviour is to support supplying a single
folder of Grafana dashboards which can then be populated
into a single folder in Grafana. Some users may wish
to have sub-folders of Dashboards, and load these into
separate dashboard folders in Grafana via a custom
provisioning file. For example, a user may have a
sub-folder of Ceph dashboards that they wish to keep
separate from OpenStack dashboards. This patch supports
sub-folders whilst not affecting the original mechanism.
