This seems a bit misplaced, since CreateFilesystem is all about
doing the initial setup of the filesystem, and the daemons are
managed in a different block of code.
In a later patch, we're going to want to allow the CRD to spin
up MDS' for filesystems that already exist. Lift the code that
sets the MDS count into the caller.

fix#2193
Fix regression introduced by PR allowing MDS config creation in init
container. This allows the new deployment-based mds clusters to scale
down where currently they can only remain constant or scale up.

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.

While creating a PVC, if the operator dies between successfully creating a rbd
image and associating it with a PV, that PVC will never be completed. A
restarted operator will also fail to complete the task as the requested rbd
image already exists. With the assumption that a PVC UID will always be unique,
this patch will try to use the existing volume and complete the PVC request.

Current code will truncate the generated RBD image in some cases,
this PR will round up the size to make sure the final RBD image
generated can cover all the required data space.
Also, corresponding unit test cases added to verify the change.

Previously, if this failed mid-way it would then throw
an exception at the first operation when retrying (because it's
trying to reweight an OSD that might not be in the map any more)

To make it more applicable to what is actually running when using the
operator the used test mon names have been replaced by the actual format
used in normal operations: `rook-ceph-mon[0-9]` instead of `mon[0-9]`.
This also removes some duplicated test code and used the already
available function for it.

Multiple file system support is still considered experimental in Ceph.
Disabling that as default in rook until such time it is production
ready.
