Progress toward issue #2003. Includes design from design doc PR #1578 Use init containers to create configuration for Ceph mgrs. There is only one init container in this design. The init container calls the Rook binary to create Ceph config files which are then shared with the mds daemon main container. Once this init is run, the main mds daemon is run. Leaving room to use the Ceph-versioned image in the future, call `ceph-mds --foreground ...` to run the Ceph mds. The refactor to using an init container also necessitated refactoring the mdses replicaset implementation to a deployment-per-pod implementation due to a chicken-egg problem. With a single container (in the before times) the Rook binary was able to call the ceph-mds daemon with an id generated from the pod name. Since the pod name is not known before runtime, and the id is one of the few params that must be specified to Ceph daemons on run, it is necessary to know the id beforehand; thus the move to a deployment architecture following the likes of the mon and mgr daemons.
