Some integration tests fail due to resources from a previous integration
run not being cleaned up properly. Instead of using 'kubectl create' --
which fails with an error if the resource already exists -- to create
resources, use 'kubectl apply' -- which does not fail for pre-existing
resources. 'kubectl apply' will give a warning that it should be used to
apply changes to resources created with 'create' or 'apply', but there
is no error.

Various kubectl helper methods return strings from calls to
create, delete, or apply resources. There is no need for this.
It is sufficient and complete to check the err from these calls to determine failure.

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.

Fix some basic spellcheck errors. Also remove trailing spaces and make
sure files have a newline (my editor does automatically).

- multiple file systems are allowed
- multiple mds instances are allowed per file system.
- a keyring is created per mds instance
- double the desired mds instances are started, half in standby mode
