It was observed that under certain circumstances
galera instances can use old IP address of the node
after pod restart. This patch changes the value of
wsrep_cluster_address variable - instead of listing
all dns names of the cluster nodes the discovery service
IP address is used. In this case cluster_node_address is set to IP
address instead of DNS name - otherwise SST method will fail.
