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.

Split the mysql alarm cluster

Fix mysql with adding ulimit -n 102400

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

Change cluster policy to availability_of_members
