During Galera bootstrap stage the following help scripts are created:
/usr/local/sbin/galera_init.sh
/usr/local/sbin/galera_bootstrap.sh
Both contain mysql root password in a plain text.
Set file permissions to 750

Issue:
During bootstrap, formula creates file in: /var/lib/mysql
If galera replica has been broken for any reason, wsrep process
calls xtrabackup to recover replica and wipes away everything in
/var/lib/mysql with bootstrap flag as well.
Now this node is not marked as deployed and galera state rerun
would try to reprovision it and fail.
Fix:
Create and check flag in: /etc/mysql/.galera_bootstrap

In case of mysql failed it shows different values for different nodes.
After this fix it ll show actual cluster size

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.

There is wrong assumption that when server pillar is
defined the node is galera master, we need to check
actually that it is enabled.

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.

Make max_connections and innodb_buffer_pool_size configurable
through soft params instead of hard.
Change-Id: Id0bb8f6b6091289275864bf4dd6a6890d11b4782
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.
Change-Id: I5dfad49a8e44a40ae87c5e8e0b033dcd73dc2837
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.

command called by service.dead state:
systemd-run --scope systemctl stop mysql.service
More common way is to shut down service using known credentials

The tag is equal to the address of the server which is quite useless
when using a Unix socket address.
