Travis Nielsen fca761c950 ceph: set the location on the mon daemon
The mon daemon in a stretch cluster now can have its location set
as a CLI param instead of setting it with a separate command.
This enables mon failover to set the location of a mon immediately
when it is joining quorum instead of having a delayed command
to set the location.

Travis Nielsen b0a63711f5 build: refactor to consolidate the rook.io/v1 package
The rook.io/v1 package was only an internal implementation detail and
does not have any CRDs that rely on it. The CRD deserialization should
handle the change in internal types without any issue. This separation
gives more flexibility for the storage providers to implement exactly
what is needed for their storage provider instead of forcing to use the
same types and risk affecting another storage provider.

Sébastien Han cb7d600841 ceph: set process working dir to /var/log/ceph
By setting the working directory of a Ceph daemon to the log direcor
(which is bindmounted to the host), we can ensure that the coredumps
will be available.

On CentOS 7 **only**, the kernel is configured with:

```
cat /proc/sys/kernel/core_pattern
core
```

which means that the coredumps will end up in the process working
directory and will be named "core".

On CentOS 8, everything is different and this won't work but still
CentOS will be able to consume this and changing the working directory
is harmless.

Sébastien Han ccb52b84e6 ceph: configurable status checks and livenessprobe
This commit allows us to configure status check for each daemon:

* "mon": health check on the ceph monitors (quorum)
* "osd": health check on the ceph osds
* "status": ceph health status check

Each check is controlled by the following settings:

* disabled: whether to disable the check (default: false)
* internal: interval to run the check
* timeout: only valid for mons, is the timeout for unresponsive mon
before failling over.

Example to disable the status health check:

```yaml
healthCheck:
  daemonHealth:
    status:
      disabled: true
```

As part of that, pod's livenessprobe can now be configured via the
following settings:

* disabled: whether to enable or not
* probe: override the current probe in place by a new one

```yaml
healthCheck:
  livenessProbe:
    mon:
      disabled: true

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.

Juan Miguel Olmo Martínez b4ae856c70 Ceph: Assure mon canary pods deletion
If for any cause the operator processing a mon failover is restarted, the
mon canary pods created in order to get the right placement for this
kind of pods can remain in <pending> state forever.

The following labels have been added to the mon canary deployments:
"mon_type" = "canary"
"canary_pvc_name" = <PVC name used for the canary pod>

A separate <removeCanaryDeployments> has been implemented for
removing the dependence of the variable <canaryCleanup>.
This function uses the <canary> labels to obtain the <real>
and <existing> list of mon canary deployments in any moment.

This change, by itself, will avoid most of the problems with
pending canary pods, but as second safe guard measure a call to this
function has been added in the health check, to <force> a canary pod
deletion if the cluster of monitors is healthy and complete (this implies
that no canary pods should be present)

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

Sébastien Han db614473c2 ceph: fix race condition on crd child update
We recently discovered a race condition which happens not to update the
child CRDs when CR image changes.

The race happens under the following sequence:

* orchestration onAdd() is called when the operator image restarts
or its image updated
* the orchestration then goes into processing mon/mgr/osd
* during this the cluster CR is updated so onUpdate() is called,
however, onAdd() is not done yet for child CRDs (mds, rgw)
* onUpdate() runs against the cluster CR and updates the cluster images
* by the time the child CRDs reached onUpdate() from their respective
ParentClusterChanged() methods, the image is already up to date
so we were exiting since our check for updating
these resources are based on the cluster image version

To fix this, we changed the comparison, but using isUpgrade instead and
slightly changed the way isUpgrade operates. So now, isUpgrade is true
even if the Ceph version is identical which allows us to verify whether
or not the image changed.
