This avoids the need to use a proxy, or some other means, to connect to
Prometheus. This is disabled by default and can be enabled by setting

This commit adds the ironic-prometheus-exporter, following the
conventions used by the previously integrated exporters. '[The] Ironic
Prometheus Exporter is a Tool to expose hardware sensor data in the
Prometheus format through an HTTP endpoint.'[0]

Prometheus has been enabled in CI jobs to ensure test coverage.

Use case: exposing single external https frontend and
load balancing services using FQDNs.

Support different ports for internal and external endpoints.

Introduced kolla_url filter to normalize urls like:
- https://magnum.external:443/v1
- http://magnum.external:80/v1

Replaces the instance label on prometheus metrics with the inventory
hostname as opposed to the ip address. The ip address is still used as
the target address which means that there is no issue of the hostname
being unresolvable. Can be optionally enabled or set to FQDNs by
changing the prometheus_instance_label variable as mentioned in the
release notes.

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``.

This change replaces ElasticSearch with OpenSearch, and Kibana

Prometheus is creating user and granting permissions
to database from which is gathering metrics. This
process is different when haproxy/proxysql is used.

Proxysql:

  - kolla-ansible should use root_shard_ID user to connect
    to ProxySQL endpoint and it is routed to proper shard.

Haproxy:

  - kolla-ansible should use root user to connect to HAProxy
    endpoint and that's all.

If proxysql is not used, mariadb role will not create user
shard_root_ID user in bootstrap (from my perspective of view
it should), and therefore it will fail when HAProxy is used.

This patch is just fixing user to connect.

Starting from v1.5.0 of the exporter, OS_COMPUTE_API_VERSION can be set
to configure the Nova API version to be used [1]. Microversion 2.1 can
be used to keep metrics unmodified from the previous exporter version
deployed by Kolla (v1.3.0).

Support it with prometheus_openstack_exporter_compute_api_version,
defaulting to using the latest version.

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:

Kolla has removed the Volume V2 API by default since OpenStack Wallaby.
However, openstack-exporter attempts to use the Volume V2 API by
default, resulting in clean installs failing to fetch Cinder metrics
in Prometheus.

This patch updates the clouds.yml configuration file for
openstack-exporter to use the Volume V3 API instead.
