Alexander Trost a87c00ddee ceph: allow user to add labels to pods
This allows users to specify additional labels to be added to the components
created by the Rook Ceph operator.
Additionally the rbd mirrors are now getting their annotations and
labels set.

Travis Nielsen ce92249725 ceph: continue with memory limits below min settings
The operator will now allow the resource limits to be applied below the
recommended minimums. In small clusters, even the recommended minimums
may not be necessary. A warning is still printed to the operator log,
but we allow the configuration to continue.

Travis Nielsen 06c21954e1 ceph: labels are immutable for match selectors
The labels cannot be updated on a deployment match selector.
In v1.4 a new label was added for ceph_daemon_type that is intended
to be on the pod labels, but cannot be applied to the match selectors.
Therefore, we suppress any new labels that are added to the daemons.

Travis Nielsen e74c7eaef8 ceph: refactor context and clusterInfo passed to the ceph commands
To provide more context for executing commands in a ceph cluster,
the full clusterInfo is now passed to the ceph execution commands.
All information about the cluster will now be available throughout
all the areas of the operator. The namespace, ceph credentials,
mon endpoints, and other info is a core part of that cluster info.

Arguments passed through the controllers are also simplified for
mons, mgr, osds, and other daemons where the parameters had
become too complex.

Sébastien Han c7f255a0e8 ceph: add the ability to set any pool property
We can now explicitly set any property on a given pool by using the new
Property field in the CephBlockPool Spec.

Also, this fixes the case where both `CephBlockPool` and `CephCluster`
are created at the same time. When Rook creates the pool, the cluster is
still being bootstrapped and the global option
`osd_pool_default_pg_autoscale_mode` has not bee set yet. So the pool
gets created but its `pg_autoscale_mode` property is set to `warn`
instead of `on`.

Sébastien Han f27fd207ce ceph: convert the CephCluster controller to the controller-runtime
This is the final conversion to controller-runtime conversion. This time the
CephCluster CRD has been converted to use the controller-runtime
library.
The controller incorporates all the previous watchers too, so the Node
and hot-plug configmap are been watched too.
Only the operator setting configmap is not being watcher since it's not
related to the CephCluster CRD.
Not only the patch converts to controller-runtime but also tries to
re-organize the tree of the repo to actually make the code more
readable and have better functions/methods/tests separations.

Travis Nielsen 269cfe1199 ceph: update status on current version of resources
When updating the status on resources sometimes the update fails due to
the resource being an outdated version. This frequently occurs when
the same reconcile loop updates the status multiple times, or the finalizer
is added, or some other update to the resource. Upon the next reconcile
the error would generally go away since the status or finalizer didn't
need to be updated multiple times. But now the error is not expected
since the controller will retrieve the latest version of the resource
immediately before attempting to update it.

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.

We now always perform ok-to-stop change when the deployment is going to

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.

Juan Miguel Olmo Martínez f62b2fa305 Ceph: MDS pod placement adheres to fault domain topology
With this modification is guaranteed that at least 1 MDS pod is going to be
placed in each of the available zones in the k8s cluster.
This would be improved in the future using:
<Pod Topology Spread Constraints> (still in alpha state since kubernetes V.1.16)

This modification obtain the number of zones in the k8s cluster and appends an
<antiaffinity> term using the topologyKey
<topology.kubernetes.io/zone> in the same number of MDS pods.
In the case that will be more MDS pods than zones, the <antiaffinity> term won't
be added in these extra pods.

Important Note:
The antiaffiniy term only will work with nodes labeled using the NEW label:
 <topology.kubernetes.io/zone> present in k8s V.1.17 clusters.
For previous versions of k8s clusters the label used is:
 <failure-domain.beta.kubernetes.io/zone>
And therefore, in this kind of clusters this modification won't work.
