Projects which may use Kafka include Monasca and Oslo
messaging. Initially it will be possible to
deploy a single Kafka cluster which may be shared
among clients. Support for running multiple Kafka
clusters may be added in a future change. This
change also configures logging for Kafka server,
state-change and controller logs.

Previously ironic inspector logs were not being collected, as they are
stored in /var/log/kolla/ironic-inspector/ rather than
/var/log/kolla/ironic/. This change modifies the fluentd input
configuration to use the correct directory.

Also adds the ironic-inspector service to the fluentd programname
rewrite rule.

In some scenarios it may be useful to apply custom filters to logs
before forwarding them.  This may be useful to add additional tags to
the messages or to modify the tags to conform to a log format that
differs from the one defined by kolla-ansible.

Configuration of custom fluentd filters is possible by placing filter
configuration files in ``/etc/kolla/config/fluentd/filter/*.conf`` on
the ansible control host.

- Sets the hostname on rabbitmq and mariadb log messages
  according to the local host.
- Sets the hostname on syslog log messages by extracting it
  from the syslog message. In many cases this will be the
  same as the local host, but it may also be a remote host.

The current syntax of Ubuntu fluentd rewrite rules are not supported
anymore, reference to this commit[1].
According to the build of this patch[2], The Centos has no such isuue.
Only Ubuntu needs to be upgrade to use the <rule> section.

* Centos use 01-rewrite-0.12.conf.j2
* Ubuntu use 01-rewrite-0.14.conf.j2

Fluentd config actually used two keywords to named log level:
"log_level" and "severity_label".
This doesn't allow to search and sort ALL logs in Kibana using a unique
field (ex: log_level).
This fix standardize log level keyword naming.

Actual Fluentd config doesn't manage multiline log pattern like:

2017-08-16 21:41:03.097 7 WARNING oslo_config.cfg [-] Option "firewall_driver" from group "DEFAULT" is deprecated for removal (
nova-network is deprecated, as are any related configuration options.
). Its value may be silently ignored in the future.

This log will generate 1 Fluentd event for each line (in previous
example 3 events).
This is really a wrong behaviour and made Kibana interface not friendly.
This patch uses a multiline parser.

Actually a unique 'tail' source is used for all logs files in
kolla/*/*.log.

So log files from services like: chrony, elasticsearch, etcd, grafana,
influxdb, kibana, mongodb... are actually processed by our Fluentd
config, but should not cause all following config will failed to parse
them. It just uses CPU for nothing cause they will
never match the following filters:
* record_transformer => add Hostname, Logger, programname field
* rewrite_tag_filter => rewrite 'programname' TAG if needed

Hence these filters should only be applied to Openstack services logs to
avoid CPU usage.

Furthermore WGI and Apache logs files must be treated differently.
