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.

This reverts commit 91321ac8.

The reasoning given in this commit is incorrect. Keystone/oslo.cache
uses memcached hosts based on a hashing of the key to determine which
memcached host to check. If you have different configured memcached
servers per keystone deployment you have a mis-configured deployment.

Any RESTapi should be capable of roundrobin load-balancing. I am not
familiar with the Murano case with uploading a package, but this change
also does not address Murano at all.

As far as Horizon goes, that hasn't had a problem with shared backends
since the beginning because we use memcached servers with a shared
secret key [1].

All this change has done is lowered the efficiency of loadbalancing
keystone.
