Wait for the mon-canary pods to be terminated before starting the actual
mons. When topology spread constraints are added to evenly spread the
mons, then pod-anti affinity does not allow mons to be created on the
same node where other mons are running, this also includes the
mon-canary pods. We delete the mon-canary pods and then start the actual
mon pods. Sometimes the termination of the canary pods might take more
time, so schedular won't schedular mon pods on that node.

Implement CephX key rotation for Rook's client.admin user.
Admin user rotation is risky, so this has been tested extensively both
in unit tests as well as by manually injecting failures during runtime.
In testing, all failures were able to be recovered by the recovery
routine.
A mutex is also added to help ensure that two simultaneous admin key
rotation processes cannot be running simultaneously for any given
namespace. The mutex is tested in unit tests, and it was verified during
runtime via manual testing.

Ceph to change how the `mon.` key is tracked internally. Rook's mon key

Cleanup up overall usage of CephX statuses in CephCluster.
Convert all CephX statuses to non-pointer types. There is no specific

not a risk of nil pointer exceptions in all the various Rook controllers
for upgraded clusters.
Move initialization of CephCluster CephX status items to

1. 'Uninitialized' state was being set for external CephClusters where
CephX statuses are not relevant.
2. 'Uninitialized' state was being set for upgraded clusters whose key

During mon failover, if a mon is assigned to a node
but the node does not exist, the mon should be failed
over immediately instead of waiting for a 10 or 20
minute timeout. If the node does not exist, the mon pod
will be in a pending state until the failover is finally
triggered, and no point in waiting that long if the
node is gone.

When a mon is failed over, the old mon is left in mon quorum
until the new quorum is confirmed in quorum. When host networking
is enabled, this may result in two mons being in quorum with the
same ip, if the new mon is scheduled on the same node as the
down mon. This results in daemon crashes in the cluster since
they are confused by multiple of the same ip in the mon map.
The solution is to avoid scaling down the bad mon when host networking
is enabled. This will ensure the new mon is not scheduled on the
same node as the previous mon. With host networking, either another
node is necessary or the original mon must come back online to
restore quorum.

This change addresses a permission issue where mon pods crashloop
on some Kubernetes setups with SELinux enabled, even when
ROOK_HOSTPATH_REQUIRES_PRIVILEGED is set.
To resolve this, a new function makeMonSecurityContext() was introduced
to explicitly set runAsUser: 0 at the pod level for mon pods
when the environment variable ROOK_CEPH_MON_RUN_AS_ROOT is set to true.
Additionally, the function previously named PodSecurityContext() was renamed
to DefaultContainerSecurityContext() to avoid confusion between
container-level and pod-level security context configuration. All container
SecurityContext usages across Ceph daemons were updated to reflect this change.
This ensures the root user configuration is applied
automatically and consistently in environments where it is required
for mon pod startup, while preserving clear separation of container
and pod-level security logic.

All existing controller runtime watches are converted to use "typed"
handlers and predicates instead of operating on `client.Object`. The
intent is to be bug for bug equivalent with the existing logic while
replacing run time type assertions and switch statements with compile
time type constraints and type casts. In several cases, functions using
assertions were split up such that each function only handles a single
Kind at a time. It is hoped that this will improve readability and
maintainability while facilitating future refactoring such as migrating
some watches to using IndexFields.
Of particular note is that the massive switch statement in
`WatchControllerPredicate()` from
`pkg/operator/ceph/controller/predicate.go` has been replaced with
generics, reflection, and splitting the obc logic into its own predicate
function. There are still many helper functions operating on
`client.Object`. These were not updated unless required by the compiler
in order to limit the size of this change. The type safety of these
funcs should be improved as followup work.
It is strongly suggested that going forward, handlers and predicates
only handle a single Kind (generic or not) and that switches / type
assertions are heavily discouraged or forbidden. This PR removed all
but a single switch statement in a predicate, which should be addressed
in future work.

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.

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 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.
