ceph: rgw service selector should not change
ceph: rgw service selector should not change

If the selector changes on the rgw service, during upgrade the
clients will briefly not be able to connect to the rgw pods.
After all the pods are updated with any new labels, the connections
would be restored, but we want to avoid that temporary outage.
