Sébastien Han 583791c45c core: move clusterInfo code to the controller package
The CSI package needs to load clusterInfo, today this code is in the mon
package which makes the call of LoadClusterInfo impossible without
having a circular import.

Sébastien Han 32998cbda4 core: do not dereference a non-pointer
In this case `oldMappingToGo` and `newMappingToGo` were not pointers so
there is nothing to dereference.
This happens when the monitors endpoints configmap is updated, but only
on the pool and file controllers. They are watching for changes on that
configmap so that they can reconcile and upate the bootstrap peers token
when replication is enabled.

Sébastien Han 5404ec13a2 core: dereference pointer before trying to compare with deepequal
Prior to this, we were comparing a pointer (the memory address) with a
struct. This was obviously always failing and returned false. We must
dereference the pointer to access the data contained at that memory
location.

Sébastien Han b578f916e7 ceph: add fs mirror config
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
        name: myfs
    lastChecked: "2021-07-01T14:16:29Z"
  phase: Ready
  snapshotScheduleStatus:
    lastChecked: "2021-07-01T14:16:29Z"
    snapshotSchedules:
    - fs: myfs
      path: /
      rel_path: /
      retention: {}
      schedule: 24h
```
