The patch deletes deprecated cmd.run function which actually
was defined in salt 2016 as alias for cmd.shell therefore this
change supports backward compatibility.

When SSL enabled, /etc/mysq directory is created by salt.minion
state with 700 permissions. It prohibits mysql from reading config
file as normal mode is 755. This patch ensures that mode for
/etc/mysql and /etc/mysql/ssl have correct rights.

This patch removes separate state galera.ssl as it was previously
wrongly introduced. Instead include ssl tasks to master/slave when
ssl is enabled.
This fixes missing requirements when applying separate states.
Ensure that mysql package is installed before changing group
ownership for ssl files to mysql, as group will be added by mysql
packages.

Fix ssl inital configuration. SSL settings are not applied during
service reload, we have to add them during initial galera cluster
start.

command called by service.dead state:
systemd-run --scope systemctl stop mysql.service

More common way is to shut down service using known credentials

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
