In case of RDR with multus, the file which contains peer

since rbd commands in multus, commands are run via mgr

This change cleans up and standardizes import statements across the Ceph operator code. It removes redundant or duplicate imports and reorganizes alias names for improved clarity and consistency. Additionally, the ST1019 exception was removed from .golangci.yaml now that the code complies with the rule.

Adopting with new fields so the status is correctly synced,

When a rados namespace is deleted, it cannot be purged
until its images and snapshots are deleted. Now a condition
is being added to the rados namespace CR status so the user
does not need to read the operator log to discover the cause.

this commit add support for mirroring b/w implicit rados namespace and
defined rados namespace. To support this, rook will treat `<implicit>`
name on cephblockpool as `""` empty string. This will allow mirroring
b/w implicit and defined radosnamespace.

Implements #14733. Allows to set IDs of external mons to
Cluster CRD. Rook will not remove external mons from quorum
and will add external mon addresses to mon endpoints.
Use-case for external mon is to maintain quorum for 2-AZ
k8s cluster in case of zone outage.

For image mode mirroring, if cephBlockPool.Pool.Spec.Mirroring.Enable
is set to false, then remove the peer cluster and disable mirroring on
all the pool if the user has disabled mirroring on all the pool images.
If mirroring is not disabled on all the pool images, then reconcile will
fail asking the users to manually disable mirroring on those images.

The built-in pools device_health_metrics and .nfs created by ceph
need to be configured for replicas, failure domain, etc.
To support this, we allow the pool to be created as a CR.
Since K8s does not support underscores in the resource names
the operator must translate this special pool name into
the name expected by ceph.
This also sets the basis for allowing filesystem data
pools to specify the desired pool name instead of requiring
a generated name.

The monitor list was not sorted, so each time we were reconciling, the
peer secret token will see its content updated with randomized
monitors. This would enter our predicate and trigger a reconcile.
Potentially an endless one, if the randomized list is already different.

They are scenarios where the mirroring information want to be shared
between clusters prior to creating pool. Because the bootstrap peer
import command needs a pool name to operate this is not suitable. So
additionally now each time the cluster is reconciled and on any new
clusters a new secret will be created that contains a boostrap peer
token. It can be exchanged with another cluster.

Instead of having the RBDMirroringPeerSpec in the RBDMirror CRD we want
to move it on the CephBlockPool CRD so that each pool can have its own peer.
This enables pool to re-use an existing peer secret if it points to the
same cluster peer.So we don't need to duplicate secret peer anymore.

- Add warning for the user to disable mirroring manually for `Mirroring.Mode == image`
- Stop the mirroring health checker goroutine
- Reset the mirroring health check status in the CR.

Similarly to block volume replication, Ceph is capable of replicating the
content of a Ceph Filesystem from one cluster to another.
For this, during the 1.6 cycle, we introduced a new CRD called
CephFilesystemMirror which effectively deploys a cephfs-mirror daemon.
However, configuring peers to enable replication between two clusters
had to be done manually.
Also various bug fix made it in Ceph eventually and the minimum required
version for this to work is to run on Ceph Pacific 16.2.5 at least.
So the automatic configuration of Ceph Filesystem peers is now possible.
By editing the CephFilesystem CRD, you can now turn on mirroring:
```yaml
mirroring:
enabled: false
# list of Kubernetes Secrets containing the peer token
# for more details see: https://docs.ceph.com/en/latest/dev/cephfs-mirroring/#bootstrap-peers
peers:
secretNames:
- secondary-cluster-peer
```
Also, the mirroring status is displayed in the CR status:
```
status:
info:
fsMirrorBootstrapPeerSecretName: fs-peer-token-myfs
mirroringStatus:
daemonsStatus:
- daemon_id: 4186
filesystems:
- filesystem_id: 2

`rbd mirror pool peer bootstrap create` will use cluster fsid by default, so specifying --site-name shouldn't be needed at all.
Signed-off-by: Sébastien Han <seb@redhat.com>
Removing the site's name helps us reducing the size of the rbd-mirror
socket path which under certain circumstances could exceed the system
limit.
Also, the namespace information is not that relevant, the cluster FSID
is.

Finally! We can now stop editing manually our crds definition. Simply
run `make crds-gen`. These two files:
* `cluster/examples/kubernetes/ceph/crds.yaml`
* `cluster/charts/rook-ceph/templates/resources.yaml`
will be autogenerated for us.
We rely on the controller-gen tool, it reads our API definitions from
`pkg/apis/` and produces the CRD files accordingly.
It uses "markers" to add extra yaml fields to the CRD, for instance we
have a lot fields with:
```
nullable: true
x-kubernetes-preserve-unknown-fields: true
```
The corresponding API type markers are:
```
// +kubebuilder:pruning:PreserveUnknownFields
// +nullable
```
For more API convention see
https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#optional-vs-required
and for the markers see: https://book.kubebuilder.io/reference/markers/crd-validation.html

Now, we can schedule snapshots on pools from the CephBlockPool CR when
the pool is mirrored.
It can be enabled like this:
```
mirroring:
enabled: true
mode: pool
snapshotSchedules:
- interval: 24h # daily snapshots
startTime: 14:00:00-05:00
```
Multiple schedules are supported since snapshotSchedules is a list.

Rook is now capable of configuring mirroring between sites. The
implementation works at different levels:
* CephBlockPool: which introduces a new `mirroring` configuration as well
as `statusCheck`. When turned on, Rook will enable mirroring on the
pool. It will also create a bootstrap peer token and store it in a
Kubernetes Secret. The name of that Secret can be found in the Status
field of the CephBlockPool CRD. This token can be fetched and used by
other clusters to configure the site as a peer. Mirroring can be
configured either at the pool or the image level.
* CephRBDMirror: which introduces a new `peers` configuration allowing
Rook to connect to peers by passing a Secret name. The administrator will
create a Kubernetes Secret with 2 keys: 'token' for the bootstrap peer
token and 'pool' for the name of pool. Once detected the rbd-mirror
controller will go ahead and import the peer configuration.
Pool mirroring status example:
```

rbdMirrorBootstrapPeerSecretName: pool-peer-token-test
