When a mon is failed over, the new mon is started before the old mon
is removed from quorum and purged from the cluster. If the mon has
anti-affinity, in small clusters or specific toplogies where sufficient
nodes are not available, the new mon may be prevented from starting simply
because the dead mon pod still exists. To ensure a clean failover, the
dead mon pod must first be stopped before the new mon is started.

For external cluster, it is not an issue to have a mon count set to 0
since Rook is not deploying/managing the monitors.

Based on the feature of metadata PVC for OSD: #4818, add the wal device.
For this, you need to create a new volumeClaimTemplates, its name must be "wal", if "wal" is
set, "metadata" device will refers specially for block.db device, and "wal" refers for block.wal
device in BlueStore.
A template will look like this:
```
volumeClaimTemplates:
- metadata:
name: data
spec:
resources:
requests:
storage: 10Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
storageClassName: gp2
volumeMode: Block
accessModes:
- ReadWriteOnce
- metadata:
name: metadata
spec:
resources:
requests:
storage: 6Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, io1)
storageClassName: io1
volumeMode: Block
accessModes:
- ReadWriteOnce
- metadata:
name: wal
spec:
resources:
requests:
storage: 6Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, io1)
storageClassName: io1
volumeMode: Block
accessModes:
- ReadWriteOnce
```
We now map block, block.db and block.wal directly inside the container instead of
running ceph-volume activate.

The cluster CR status needs to be updated with the latest object
instead of a cached copy or else it could fail if there is some
other update. Using the Rook clientset ensures it is the latest
instead of using the cached controller runtime object.

The service selector labels cannot be updated during the upgrade or else the
mon commands will not respond until the mon deployment is also updated.
Since there is a mon command to check for the ceph versions before the
deployment is updated, the operator would remain stuck during the upgrade.

We can now encrypted OSD device that were provisioned via a storage
class using the PV interface.
The encryption works at the storageClassDeviceSets level, which means we
can have encrypted and non-encrypted sets.
Using the new key `encrypted` we can turn it on.

The labels cannot be updated on a deployment match selector.
In v1.4 a new label was added for ceph_daemon_type that is intended
to be on the pod labels, but cannot be applied to the match selectors.
Therefore, we suppress any new labels that are added to the daemons.

This can help users identify the daemon type similarly to how
'ceph_daemon_id' helps identify the daemon ID. This also makes it so
scripts users create don't have to parse "app=rook-ceph-<daemonType>"
into "<daemonType>" if they desire that bit of info.

using defer for closing file which are open
for writing is not safe. so closing file again
following below steps:
1. open files
2. defer file.close()
3. write
4.file.close()
these will make sure files are closed.

File permissions need to be reduced to the minimum to avoid config
files from being accessed. While a connection to the pod would be
required to access the files, min privileges are set just as
another layer of security. This fixes gosec error G306.

This commit fixes where there are areas in which files and directories are
written and created with statically defined permissions. Many of these
permissions are rather open, potentially allowing other system tenants to
view and interact with their contents, which may be sensitive.
Fixed G303: Poor file permissions used for directory by using the most narrow permission
