Usage:

  galera:
    master:
      innodb_buffer_pool_size: 1024M
    slave:

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

Galera master installation hangs on installation
mysql-server-wsrep-5.6. It seems that log_error is not working,
because of next message: "mysqld_safe Can't log to error log and
syslog at the same time. Remove all --log-error configuration
options for --syslog to take effect." Using "syslog = yes" instead
of log_error makes it works without any other changes.

Closes-bug: PROD-9065

Bug: After deployment of linux formulas and salt states
/etc/security/limits.conf are not applying, as result connections
to mysql failed with error (pymysql.err.OperationalError)
(1040, u'Too many connections')

Solution: create mysql.overide, where ulimit is set to 102400

Closed-bug: PROD-8427

Because the cluster isn't managed by Pacemaker, using
majority_of_members is misleading.

This patch enables support for Grafana and provides a new dashboard.

This also installs 2 additional packages (libdbd-mysql and
python-pymysql) that are required for running the collectd plugins.
