Remove separate galera.ssl state

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.
