fix(fencing): change mdb controller to use namespace for checking status

This commit changed mdb controller to make use of cephCluster's namespace instead of cephCluster's name for checking the ceph health as the ceph config is located in the cephCluster's namespace folder which can makes mdb controller fail when rook operator is deployed in any other namespace apart from rook-ceph.
