On a running galera cluster, we don't want to unintentionally allow a galera_cluster_name from changing. This will cause a cluster to fail to start (if the nodes are restarted sequentially) as the cluter name value has changed. To ensure we can still change this value, a new "galera_force_change_cluster_name" variable is added, which can be set to "True" in order to change the cluster name.
