Andy McCrae bf3480a7ff Prevent galera_cluster_name from changing. 
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.
