Adds a new configuration file that provides fluentd with an appropiate regex to match with OpenvSwitch logs in both default files.

The regex is segmented with variable as to isolate the relevant parts of each log message.

This change adds the dnsmasq.log for the ironic-dnsmasq container and
also enables more verbose logging when debug logging enabled.
This can be triggered globbaly via 'openstack_logging_debug' or per
service via 'ironic_logging_debug' or 'neutron_logging_debug'.

This patch adds support for integrating Prometheus with Fluentd.
This can be used to extract useful information about the status
of Fluentd, such as output buffer capacity and logging rate,
and also to extract metrics from logs via custom Fluentd
configuration. More information can be found here in [1].

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.

Currently the logs tagged with infra.mariadb.xinetd flow into
elasticsearch with no hostname or programname attach, thus making
navigating the logs very hard.

The quick fix is renaming the tag to infra.mariadb-xinetd, which is just
enought to ensure the logs are processed correctly with the existing
filters.

The Monasca Log API has been removed and in this change we switch
to using the unified API. If dedicated log APIs are required then
this can be supported through configuration. Out of the box the
Monasca API is used for both logs and metrics which is envisaged to
work for most use cases.

In order to use the unified API for logs, we need to disable the
legacy Kafka client. We also rename the Monasca API config file
to remove a warning about using the old style name.

WSGI log files use a different input configuration than OpenStack log
files. Currently this depends on log files matching either *-access.log
or *-error.log. Some services use *_access.log or *_error.log, so are
not parsed correctly.

This change modifies the fluentd configuration to accept an underscore
or hyphen for WSGI log file names.

Monasca Python service logs prior to this change were being dropped
due to missing entries in the Fluent record_transformer config file.
This change adds support for ingesting those logs, and explicitly
removes support for ingesting Monasca Log API logs to reduce the risk
of feedback, for example if debug logging is turned on in the Monasca
Log API.

Presently, errors can appear in Fluentd and Monasca Log API logs due
