Failure to create a keyring prior to creating a deployment
dependent on that keyring created a race conditition resulting
in an intermittent and unnecessary pod failure. This change
creates a keyring prior to deployment creation for MDS
daemons.

The command `fs new` already enable the application pool settings for
the cephfs pools so we don't need to run that command again.

The resources for rgw, mds, and nfs were being cleaned up explicitly when
the CR was deleted. This is legacy from before the owner references were
set on the CRs. Now the owner references are set to the appropriate CRs so
the resources will be cleaned up upon deletion of the specific CR
rather than the cluster CR.

A new CRD property `PreservePoolsOnDelete` has been added to Filesystem(fs) and
Object Store(os) resources in order to increase protection against data loss.
If it is set to `true`, associated pools won't be deleted when the main
resource(fs/os) is deleted. Creating again the deleted fs/os with the same name
will reuse the preserved pools.

From now on, Rook will only perform check before upgrades when there is
an actual upgrade. So if the Ceph image changed and a new version is
desired Rook will go through all the daemons and update them one by one
and perform checks in between.

When configuring an external cluster the orchestration of discover and all the ceph
daemons will be skipped. The operator will still watch for the creation of
crds for this namespace. When a filesystem, object, object user, or
ganesha crd are created, the operator will simply print an error
to the log.

It's quite convinient to expose /var/log/ceph so that we can decide to
activate logs locally on the machine and see what's going on.
This is only a placeholder when a daemon is stuck crashlooping and we
want to allow administrator to gather log files.
We still do not log on file but this can be activated via a config
option passed to the centralized config option store.
For some daemons, which typically do not store any data (rgw, rbd-mirror
and mds) we had to propagate dataDirHostPath from the cluster spec to
each creation call so that the bindmount can happen.

A ceph filesystem was brought down by marking the filesystem
as down and individually failing the MDSes. From nautilus onwards,
this could be more simply and efficiently done by using
`fs fail` command. See,

The basic idea here is to replace the release name in the ClusterInfo
object with the fine grained version information queried at runtime.
This patch also removes the Name field from the cluster spec, which was
also runtime determined and was redundant with ClusterInfo relase name.

From ceph mimic (13.x) onwards, `mds deactivate` command is
deprecated. To scale down the number of active MDSes of a filesystem,
it's sufficient to set the desired number of active MDSes using
'max_mds' setting, and is no longer required to individually
deactivate the unwanted MDSes.

The MDS mds_standby_for_*, mon_force_standby_active, and mds_standby_replay
configuration options have been obsoleted. Instead, the operator may now set
the new "allow_standby_replay" flag on the CephFS file system. This setting
causes standbys to become standby-replay for any available rank in the file
system.

Configure the Ceph mds daemon completely from the operator a la the
recent changes to the Ceph mon and mgr operators.
Create the mds deployments first and then
create the keyring secrets for them with their owner reference as the
corresponding deployment. This will mean that the secrets do not need to
be micromanaged. When the deployment is deleted, the secret is also
deleted. This has not been necessary for the mons or the manager since
the mons share a keyring with a lifespan of the cluster, as does the
mgr, which currently has single-mgr support only.

design/external-management.md says that we should allow specifying
Filesystems that have no pools. When this is done, the CRD should
interepret that as a request to just manage the MDS daemons without
creating a new filesystem.
Don't fail the verification if there are no data pools in the spec,
and just skip creating a new filesystem if that's the case.
Also, add a testcase for this usage.

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

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.
