OpenDaylight logs have different format than openstack,
is a karaf log with java error traces.
This PS add required config to make fluentd parse properly
ODL logs.

There are cases when we can lost original timestamp field given from
logs, like when we send our logs to the next fluentd forwarder in chain
of forwarders, it will rewrite our timestamp by default. Save
`Timestamp` field explicitly to avoid such situation and be able to
reconstruct messages date and time.

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.

- 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.

By default the syslog input plugin won't extract the
log level from a syslog message. By setting the priority
key, the log level is extracted.

The following warning logs appears in fluentd container:

[warn]: pattern not match: "170908 21:34:12 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql/"

This patch fix it

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.

Disable the additional watch timer (enable_watch_timer).
Setting this parameter to false will significantly reduce CPU and I/O
consumption when tailing a large number of files on systems with inotify
support.

Libvirt logs are not managed by Fluentd. It can be very helpful to
debug 'booting' issue on KVM.

'progname' is actually only fullfilled for Openstack services logs.
They are missing for MariaDB and RabbitMQ logs.
When using Kibana, "progname" field appears empty, hence it's difficult
to known where logs comes from.

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.

Fluentd actually parse all files in /var/log/kolla/*/*.log as Openstack
services files.
Dnsmasq file /var/log/kolla/neutron/dnsmasq.log, must be add to

"/var/log/kolla/neutron/dnsmasq.log unreadable. It is excluded and would
be examined next time."
