This is the first phase CockroachDB part of three phases to improve and
rework the Rook documentation for better user accessibility to the Rook
projects and with that the storage providers.
Phase two is about automatic generation of CRD documentation and phase
three is about reworking the docs themselves and, e.g., examples for
CRDs and certain use cases.

The node labels were already supported for zones and regions to add to
the CRUSH map. Now all layers of the CRUSH map will be supported
with the new labels such as topology.rook.io/rack.
The labels will be detected at the osd startup time
similar to the zone and region labels already being detected.

This will be helpful to list the CSI drivers deployed
in the kubernetes cluster. if we have N number of
CSI drivers deployed in the cluster, the user can
query kubectl get csidriver and get the list of
registered CSI drivers and it requires kube 1.14+
and also the functionality is disabled by default

OSDs can be removed automatically with the current mechanism if a new
setting removeOSDsIfOutAndSafeToRemove is set to true. The default for
all new or upgraded clusters should be false.

The osd-prepare jobs should not inherit osd resources since this might
cause scheduling issues.
Instead, we can now use the new CRD property `prepareosd` in the resource section.
Refer to the documentation for more details.

- Added check to skip OSD on pvc provisoning if the minimum k8s version requirement is not met.

We now differentiate the cases where:
* we only consume the external cluster
* we consume the external cluster as well as creating stateless
resources in Kubernetes (bootstrap mds,rgw, nfs)
This is mostly controlled via the image property spec. If not defined,
not extra CRs won't be able to be created.
Now the external cluster feature supports Ceph cluster as of Luminous 12.2.

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.

This is round 2 attempting to add the mergify engine in Rook. In this
case, we only use the backporting and automerge features.
* auto backport: set a label on your PR and a backport PR will be
automatically created under the right branch
* auto backport PR merge: if the backport PR passes CI, mergify will
merge it.

The configmap for advanced configuration can be created before the
cluster is created. In that case, the daemons will all pick up the
settings the first time they are started. Otherwise, the daemons
need to be restarted

different path, with this PR kubelet path
can be configured for CSI.

On rare occasion, the ceph checks might not be 100% correct and the user
might decide to force an upgrade anyway.
Correctly, if we are in an upgrade, we perform `ok-to-stop` check for
each daemon, if one of them fails, we retry and eventually fail.
They are corner-cases where users would like to force the upgrade anyway.
Enhance the new CR property: "skipUpgradeChecks: true".

This adds a list of unusable directories paths to the Ceph Cluster CRD
doc page and the Ceph operator validation code. Reason for adding these
directories is that they are causing errors during Ceph OSD deployment.
Example: When an user wants to use `/rook` as a directory for an OSD,
the cluster deployment fails because the `mountPath`s must be unique:
```
Job.batch "rook-ceph-osd-prepare-NODE" is invalid: spec.template.spec.containers[1].volumeMounts[4].mountPath: Invalid value: "/rook": must be unique
```

The upgrade was missing some final features that were added recently
such as the pod disruption budgets. The namespaced RBAC changes also
needed to have the appropriate namespaces included if they had installed
the operator in a different namespace from rook-ceph.
