The resources for rgw, mds, and nfs were being cleaned up explicitly when
the CR was deleted. This is legacy from before the owner references were
set on the CRs. Now the owner references are set to the appropriate CRs so
the resources will be cleaned up upon deletion of the specific CR
rather than the cluster CR.

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.

From now on, Rook will only perform check before upgrades when there is
an actual upgrade. So if the Ceph image changed and a new version is
desired Rook will go through all the daemons and update them one by one
and perform checks in between.

We can now deploy all the other Rook's CRDs. They will be deployed in
Kubernetes but will consume the external cluster storage.

When configuring an external cluster the orchestration of discover and all the ceph
daemons will be skipped. The operator will still watch for the creation of
crds for this namespace. When a filesystem, object, object user, or
ganesha crd are created, the operator will simply print an error
to the log.

Refactor the Ceph NFS (Ganesha) daemon to use the new config pattern.
Use of a custom Rook binary to run NFS has been removed in favor of
instead running the required DBUS process as a sidecar. The effect here
is that the NFS Ganesha container itself may fail and restart a few
times before the DBUS sidecar is running.

The CephCluster CR contains settings that are needed by other
CRs to configure the Ceph daemons. When the CephCluster CR
is updated, the updates will now be passed on to each of the
CR controllers to ensure the daemons are updated properly
without requiring an operator restart.
When calling the controllers from another controller,
we ensure that only a single goroutine is handling
CRs at any given time to prevent contention across
multiple CRs of the same type.

The basic idea here is to replace the release name in the ClusterInfo
object with the fine grained version information queried at runtime.
This patch also removes the Name field from the cluster spec, which was
also runtime determined and was redundant with ClusterInfo relase name.

Rename createCephNFS to upCephNFS and have it take a parameter with the
old active count. Rename deleteGanesha to downCephNFS and have it take a
parameter with the new desired active count. Both the existing callers
pass in "0" for the new count parameters.
Fix up the onUpdate handler for CephNFS objects, such that changes to
the active count are reflected in the number of active servers. Have it
pass in the appropriate values when scaling servers up or down.
Finally, fix downCephNFS to shut down the highest-index servers first
and count down, instead of doing them in the order they were started.
This should eventually allow us more predictable behavior when scaling
down the number of server nodes.
