Configure the Ceph mgr daemon completely from the operator a la the
recent changes to the Ceph mon operator.
The pod spec for the mgr changed quite a bit, and instead of updating
the unit tests of questionable use, some additional unit test tools
applicable to any Ceph daemon have been added and used with the mgr. The
mgrs unit tests should now be more useful and get in the way of devs
less, and they can be used by other daemons later.

Make the Rook config-init unnecessary for mons, and remove that init
container. Perform all mon configuration steps in the operator, and set
up the mon pods and k8s environment such that only Ceph containers are
needed for running mons.
This should help streamline changes to the mons, as there will be no
need to change the `daemon/mon` code or `cmd/rook/ceph` code with mon
changes in the future.
This work starts to lay the groundwork for supporting the
`design/ceph-config-updates.md` design.
Notable new bits:
Create a keyring secret store helper for storing dameon keyrings, and
use it to store the mon keyring. Mon pods mount the keyring into a
k8s secret-backed volume.
Create a configmap store for the Ceph config file which can be mounted
into pods/containers directly to /etc/ceph/ceph.conf. Also store
individual mon_host and mon_initial_members values which can be mapped
into pods as environment variables and used in Ceph commandline flags,
enabling the mon pods to have the most up-to-date information about the
mon cluster when restarting and without need for operator intervention.

The sidecar now has a control loop, which watches its ClusterIP
Service for the `cassandra.rook.io/decommissioned` label.
If it finds it, then it decommissions and updates the label to
value "true".

Implementation of the cassandra sidecar logic.
This sidecar helps us inject our custom values during startup
and provides HTTP liveness and readiness checks.
In the future it will also be used for:
- Shutting Down / Decommissioning a cassandra instance
- Backups
- Restores

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.

Use init containers to create configuration for Ceph mons. There are 3
init containers in this design:
1. Using the Rook image, call the Rook binary to create Ceph config
files ultimately stored in a k8s EmptyDir which is shared between all
containers in a mon pod.
2. Leaving room to use the Ceph-versioned image in the future, call
`monmaptool` to generate the monmap, stored in a shared config dir.
3. Leaving room to use the Ceph-versioned image in the future, call
`ceph-mon --mkfs ...` to set up the mon filesystem on the host's disk.
Once this init is run, the main mon daemon is run. Leaving room to use
the Ceph-versioned image in the future, call `ceph-mon --foreground ...`
to run the Ceph mon.

To help with code readability, include daemons from `pkg/daemon/ceph`
as `<dmn>daemon "github.com/rook/rook/pkg/daemon/ceph/<dmn>`. This will
make it easier to understand code lines without needing to scroll up to
check the includes, as there are mon/mds/mgr/osd/rgw packages for
daemons as well as operator and cmd.

Create a cephconfig module in Ceph's daemon pkg source, and refactor the
config and keyring generation that exists in the mon package into the
new cephconfig package. The config/keyring generation code is used by
most all daemons and not just mon, so a new package is a more
appropriate place for this.
