Kiall Mac Innes 60eba01502 Improve percona cluster initialization 
* Switch from /etc/init.d/mysql bootstrap-pxc to
  /etc/init.d/mysql restart-bootstrap when bootstrapping
  a new cluster. This ensures that, even when Percona starts
  at boot, that new config is loaded and the cluster is
  bootstrapped.

* If percona fails to bootstrap or restart, ensure we do not
  touch the initialized file, allowing os-refresh-config to
  try again on the next iteration.

Installs Percona Xtradb Cluster which is Mysql+HA solution

Mysql and mariadb elements are very similar so both depend on mysql-common element which contains shared logic. See mysql-common for more details about mysql setup.

Heat

A list of IP addresses for nodes in the cluster, the host's IP adddress, and a cluster name must be defined in the heat metadata:

Metadata:
  mysql:
    cluster-name: 'my_cluster'
    host: 192.0.2.3
    nodes: 192.0.2.3,192.0.2.4
