Closes-Bug: PROD-17416

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.

The buffer_pool_size parameter should be a integer value when followed
by a memory unit (eg '1024M', not '1024.1M'). Otherwise the MySQL
doesn't start properly.

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.

Because the current timeout interval is too short in some environments.
The change also adds information messages to bootstrap scripts

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.
