Huamin Chen c56ebf2ea6 Ceph: mon should get Pods from namespace other than ceph
Currently CLUSTER and deployment namespace both default to ceph, so these
variables can be used exchangeably.But once deployment namespace changes,
MON daemonset will not be able to get its IP from ceph namespace.
This fix swaps CLUSTER with NAMESPACE and solves this problem
