- parametrized log file path
- added fluentd configuration
- introduced fluentd multi_format parser plugin

Currently error logs sent to syslog are represented
with severity ERROR, which is misleading for Notice
and Warning messages during service startup/shutdown.

Make max_connections and innodb_buffer_pool_size configurable
through soft params instead of hard.

Change-Id: Id0bb8f6b6091289275864bf4dd6a6890d11b4782

Usage:

  galera:
    master:
      innodb_buffer_pool_size: 1024M
    slave:
      innodb_buffer_pool_size: 1024M

If innodb_buffer_pool_size is not set then 35% of the available
ram will be allocated for the buffer pool.
