This enhances the stability and recovery of ceph by leveraging hostNetworking for monitors as well as OSDs, and enables the K8S_HOST_NETWORK variable within ceph-docker. This enhancement should allow recovery of monitors from a complete downed cluster. Additionally, ceph's generic "ceph-storage" node label has been split out for mon, mds, and osd.
