Kevin Carter 8c0ce1c62f Change the galera health check for better cluster health
The current galera cluster health check simply logs into a cluster node
but does not check if the node is sync'd. This can lead to an issue
where a node is placed back into the pool before it is ready. If this
happens it can lead to a broken OpenStack environment until the wsrep
received queue is processed which is especially true if the node out of
sync happens to be the primary.
