Sébastien Han 040193bb5a ceph: remove DaemonType type

Sébastien Han 7788901a88 ceph: add liveness probe to mon, mds and osd daemons
Now Kubernetes will perform liveness checks on mon, mds and osd daemons.
The command will:

* call the socket (check for existence)
* execute a command and check the return code (success if 0)

This handles the case where the daemon is stuck locally and
unresponsive. It's unlikely but not impossible.
These checks bring more robustness to the implementation.

rbd-mirror and nfs have been leftover for the following reason. The
rbd-mirror socket name is different from other daemons (could be fixed
though): /run/ceph/ceph-client.rbd-mirror.a.1.94362516231272.asok also,
the command to call would need to be changed from "status" to "rbd
mirror status" so we can keep this for a later.
The nfs ganesha has no socket only a PID file which doesn't mean much.
No PID means the process does not run so Kubernetes will already handle
this and the pod will crash loop.

Travis Nielsen a52948e7f7 ceph: continue orchestration even if osd status update fails
The communication between the operator and OSD prepare job
is done through updates to the configmap. If an update fails
to the configmap, we are anyway going to need to check the logs
for failure. So let's just log the error and make a best effort
to continue the orchestration. If the failure was temporary,
the next update to the status would succeed and likely continue

Sébastien Han c08c3ced05 ceph: add support for metadata PVC for OSD on PVC
We now support the addition of the PVC that acts as a metadata device
for a given OSD.
For this, you need to create a new `volumeClaimTemplates`, its name must
be "metadata" otherwise, Rook won't pick it up.

A template will look like this:

```
volumeClaimTemplates:
- metadata:
    name: data
  spec:
    resources:
      requests:
        storage: 10Gi
    # IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
    storageClassName: gp2
    volumeMode: Block
    accessModes:
      - ReadWriteOnce
- metadata:
    name: metadata
  spec:
    resources:
      requests:
        storage: 6Gi
    # IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
    storageClassName: gp2
    volumeMode: Block
    accessModes:
      - ReadWriteOnce
```

We now map block and block.db directly inside the container instead of
running ceph-volume activate. This is much cleaner.

Sébastien Han 92c1696bfc ceph: cleanup/trim isUpgrade variable a bit
We now always perform ok-to-stop change when the deployment is going to
be updated. This could be for various reasons like change in the spec or
a new Ceph image.
In any case, if Ceph resources are going to be restarted this must be
done carefully.

Also trimmed the isUpgrade variable, the upcoming commit will remove the
need of that variable.

Keeping isUpgrade from the controller code since we need it to detect
whether an orchestration upgrade should be triggered or not (based on
the ceph cluster status).

Also, we keep it on the child controllers so we don't go into an
orchestration phase if the cluster image hasn't changed. The child does
not need to be updated/go into its orchestration phase because the
cluster CR changed.

Sébastien Han 227d2d527a ceph: osd store refactor
Multiple things:

1. We removed all the function/methods/tests that were used to
create and manage rook legacy OSDS as well as bringing support to
Bluestore OSD only.
It also fixes various go-lint issues in the respectives files.

2. use c-v inventory to detect available devices:
Now we rely on the 'ceph-volume inventory' command to tell us if a
device is available or not.

3. implement raw mode for osd on pvc
When an OSD will be bootstrap on a PVC, the new c-v raw mode will be
used. It consists of putting block, db and wal under the same device.
Here LVM is out of the picture and the raw device is used as is. The
implementation is backward compatible so existing OSD on PVC will LVM
will continue to operate.

Removing an OSD unintentionally can result in data loss,
which is to be prevented at all costs. Rook's functionality
to remove OSDs automatically when a node was removed from the
cluster CR has led on several occasions to users having OSDs
unintentionally removed from their cluster.

If the admin decides they really need to remove OSDs they should
do it as a one-time action that they intentionally run
rather than the operator attempting to manage the deletion
with desired state. The risk of misinterpreting the desired
state, even with a typo, is too great.
