When removing a mon from quorum, there is a race condition that
can result in mon quorum going being lost at least temporarily.
The mon pod was being deleted first, and then the mon removed
from quorum. If any other mon went down between the time the
pod of the bad mon was deleted and when the mon was removed from
quorum, there may not be sufficient quorum to complete the
action of removing the mon from quorum and the operator would
be stuck.
For example, there could be 4 mons temporarily due to timing
of upgrading K8s nodes where mons may be taken down for some
number of minutes. Say a new mon is started while the down
mon also comes back up. Now the operator sees it can remove
the 4th mon from quorum, so it starts to remove it. Now say
another mon goes down on another node that is being updated
or otherwise drained. Since the 4th mon pod was deleted
and another mon is down, there are only two mons remaining
in quorum, but 3 mons are required in quorum when there
are 4 mons. Therefore, the quorum is stuck until the
third mon comes back up.
The solution is to first remove the extra mon from quorum
before taking down the mon pod.

Previously, Rook would fail to create monitors for a `CephCluster` spec that
required them to be located in distinct failure domains:
```yaml
spec:
mon:
count: 3
failureDomainLabel: topology.kubernetes.io/zone
zones:
- eu-central-1a
- eu-central-1b
- eu-central-1c
```
This was due to the fact that Rook was mistakenly getting the
`failureDomainLabel` from `spec.mon.stretchCluster.failureDomainLabel`.
This commit ensures `spec.mon.failureDomainLabel` is being used instead, which
fixes the cluster deployment for the spec above.

If the dashboard cert already exists when ssl is enabled,
we need to not restart the dashboard module. The module
should only be restarted when there is a change to the
dashboard configuration. When ssl is enabled, the dashboard
is essentially being restarted every time there is a reconcile
which is causing issues with the mgr getting blocklisted
unnecessarily by ceph during failover.

Normally the device class of an OSD is determined at provisioning
and is not updated thereafter. In some scenarios the admin may
want to force update the device class to a new value. The device
classes can be updated by first setting allowDeviceClassUpdate
in the storage spec of the cephcluster, then updating the
device class specified on the deviceSets or other OSDs.

Block devices can move between reboots. In corner cases, an OSDs block
device might move to a lower-indexed device while the previous device
does not exist. For example, an OSD on /dev/sde might move to /dev/sdd
on reboot if the original /dev/sdd died. There would be no /dev/sde
after that.
Users report that NVMe drives commonly change names, even when there are
no disk failures.
For these cases, ensure the activate script properly handles cases where
the previous disk is not present on the node and where the OSD is still
available on a different disk.

For an advanced network configuration, the mon endpoints
expected for the ceph public network may be different from
the public IP address that is set on the K8s node. When
host networking is enabled in rook, the IP address of the
node was only allowed previously. Now, the IP address
used for a mon when scheduled on a node can be determined
by setting an annotation on each node where mons can run:
network.rook.io/mon-ip: <ip-address>
This annotation must be set before the mons are created.
Mon endpoints cannot be changed after they are already
running.

When the clusters reach full, nearfull, or backfill full thresholds
ceph will raise health warnings and stop allowing IO or backfill

Currently we allow upgrade of other OSDs while migration
of OSD, due to change in backing store, is pending. This
will not work if the updated OSD ceph version does not support
the currently applied backing store. So rook will skip any
OSD upgrade if the OSD migration is pending.

When IPv6-only network mode is enabled and when mons are configured to
listen only on msgrV2 port, Rook has to add the port to the mon
--public-bind-addr in order to force mons to stop listening on the
msgrV1 port. This can cause problems for IPv6 clusters where adding
':<port>' to the end of an IP addr looks like a valid IPv6 address.
In IPv6 mode, Rook needs to set this to '[<ip>]:<port>' with the
brackets to be a non-ambiguous IPv6 address.
In IPv4 mode, Rook needs to keep its existing behavior. IPv4 mode should
also continue to be the defualt assumption if the network config isn't
specified.
If 'dualStack: true' is specified, Rook is informed that the environment
is dual stack, but Rook doesn't know which IP family to expect from the
pod IP. In this scenario, it is safest for Rook not to apply the port,
since assuming either IPv4 or IPv6 format could be incorrect. In this
scenario, mons may still listen on msgrV1 ports, but this is preferable
to an environment where mons perpetually crash.

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.
