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.
