The upgrade of the mds daemons pauses to wait for the
stopping of standby daemons before the filesystem upgrade
is completed. If there are multiple filesystems, there
could be standbys for other filesystems that will not be
stopped at the time of the upgrade of another filesystem.
Thus, the standbys may not upgrade and be stuck on the
previous version. Now, the standby upgrade will only wait
for standbys for the same filesystem.

Finish the process of deprecating holder pods by removing Rook's ability
to deploy them. The intent of this change is to make the most
superficial changes possible to accomplish this. There are still
remnants of code in Rook (particularly the CSI controller) that helped
configure or deploy holder pods. Due to the risk of breaking some
features, cleanup work of hose remnants will be deferred for future
work.

When the MDS liveness probe times out, it should not fail the probe. If
the cluster has a network partition or other issue that causes the Ceph
mon cluster to become unstable, `ceph ...` commands can hang and cause
a timeout. In this case, the MDS should not be restarted so as to not
cause cascading cluster disruption.

Someone testing the Multus holder pod removal feature encountered an
issue where the migration process failed to lead to a system state where
PVCs could be created successfully.
The root cause was found to be a ceph csi config map wherein the primary
CephCluster entry was lacking a value for the "namespace" field.
I observed this once in my development on the holder pod removal
feature, but I was unable to reproduce and assumed it was my own error.
Since this has been seen in a user environment, it must be that the
error is a race condition, and I am unable to determine the exact source
of the bug.
I do not believe this bug would be present if the code that updates the
CSI configmap were properly idempotent, but it has many conditions based
on prior states, and I was unable to determine how to resolve this
underlying impelementation pattern issue.
Instead, I opted to separate the `clusterKey` parameter into two clear
parts:
1. `clusterID` for when `clusterKey` is used as an analogue for
`clusterID`
2. `clusterNamespace` for when `clusterKey` is used as an analogue for
`clusterNamespace`
I added unit tests to ensure that SaveClusterConfig() will be able to
detect when the namespace is currently missing, and using the new
`clusterNamespace` field, it should always know what value to use as
input when correcting the bug in already-installed systems.
I also verified that this update works when the function simultaneously
removes netNamespaceFilePath entries, and that those entries are removed
properly.
Finally, manual testing also verifies the change.

Rook has been setting the application automatically on all
pools to rbd for CephBlockPools, rook-ceph-rgw for
CephObjectStores, mgr on the built-in .mgr pool,
and nfs on the built-in .nfs pool.
The legacy pool device_health_metrics is long gone
from Pacific which is no longer supported, so we can
remove special handling for that pool in the upgrade
guide and in the code.
The application setting is now available on the pool spec
although it is not expected to commonly need to override
the default applications set by Rook.
The application for CephFilesystem pools is now being
set to cephfs, where it was previously blank.

Change how Rook detects network CIDRs for Multus networks. The IPAM
configuration is only defined as an arbitrary string JSON blob with a
"type" field and nothing more. Rook's detection of CIDRs for whereabouts
had already grown out of date since the initial implementation.
Additionally, Rook did not support DHCP IPAM, which is a reasonable
choice for users. And more, Rook did not support CNI plugin chaining,
which further complicates NADs. Based on the CNI spec, network chaning
can result in any changes to network CIDRs from the first-given plugin.
All these problems make it more and more difficult for Rook to support
Multus by inspecting the NAD itself to predict network CIDRs. Instead,
it is better for Rook to treat the CNI process as a black box. To
preserve legacy functionality of auto-detecting networks and to make
that as robust as possible, change to a canary-style architecture like
that used for Ceph mons, from which Rook will detect the network CIDRs
if possible.
Also allow users to specify overrides for CIDR ranges. This allows Rook
to still support esoteric and unexpected NAD or network configurations
where a CIDR range is not detectable or where the range detected would
be incomplete. Because it may be impossible for Rook to understand the
network CIDRs wholistically while residing only on a portion of the
network, this feature should have been present from Multus's inception.
Improving CIDR auto-detection and allowing users to specify overrides
for auto-detected CIDRs rounds out Rook's Multus support for CephCluster
(core/RADOS) installations. No further architectural changes should be
needed for CephClusters as regards application of public/cluster network
CIDRs for Multus networks.
