After Failover of workloads to the secondary
cluster when the primary cluster is down,
RBD Image is not marked healthy, and VR
resources are not promoted to the Primary,
In VolumeReplication, the `CURRENT STATE`
remains Unknown and doesn't change to Primary.
This happens because the primary cluster went down,
and we have force promoted the image on the
secondary cluster. and the image stays in
up+stopping_replay or could be any other states.
Currently assumption was that the image will
always be `up+stopped`. But the image will be in
`up+stopped` only for planned failover and it
could be in any other state if its a forced
failover. For this reason, removing
checkHealthyPrimary from the PromoteVolume RPC call.

Recently the k8s.io/mount-utils package added more runtime dectection.
When creating a new Mounter, the detect is run every time. This is
unfortunate, as it logs a message like the following:
```
mount_linux.go:283] Detected umount with safe 'not mounted' behavior
```
This message might be useful, so it probably good to keep it.
In Ceph-CSI there are various locations where Mounter instances are
created. Moving that to the DefaultNodeServer type reduces it to a
single place. Some utility functions need to accept the additional
parameter too, so that has been modified as well.

Looks like cephfs snapshot size is buggy and its
getting removed in ceph fs. we cannot get the size
of the snapshot during CreateVolume call, so we cannot
do any size check at CreateVolume to check if the
restore size is smaller or not.
As we are removing this check it also fixes#3147
but we dont have any validation at CSI level for
smaller restore we need to depend on kubernetes
external-provisioner for it.

Due to the bug in the df stat we need to round off
the subvolume size to align with 4Mib.
Note:- Minimum supported size in cephcsi is 1Mib,

While creating subvolumes, CephFS driver set the mode to `777`
and pass it along to go ceph apis which cause the subvolume
permission to be on 777, however if we create a subvolume
directly in the ceph cluster, the default permission bits are
set which is 755 for the subvolume. This commit try to stick
to the default behaviour even while creating the subvolume.
This also means that we can work with fsgrouppolicy set to
`File` in csiDriver object which is also addressed in this commit.

When the Ceph user is restricted to a specific namespace in the pool, it is
crucial that evey interaction with the cluster is done within that namespace.
This wasn't the case in `getCloneDepth()`.
This issue was causing snapshot creation to fail with

There are regular reports that identify a non-error as the cause of
failures. The Kubernetes mount-utils package has detection for systemd
based environments, and if systemd is unavailable, the following error
is logged:
Cannot run systemd-run, assuming non-systemd OS
systemd-run output: System has not been booted with systemd as init
system (PID 1). Can't operate.
Failed to create bus connection: Host is down, failed with: exit status 1
Because of the `failed` and `exit status 1` error message, users might
assume that the mounting failed. This does not need to be the case. The
container-images that the Ceph-CSI projects provides, do not use
systemd, so the error will get logged with each mount attempt.
By using the newer MountSensitiveWithoutSystemd() function from the
mount-utils package where we can, the number of confusing logs get
reduced.

As we added support to set the metadata on the rbd images created for
the PVC and volume snapshot, by default metadata is set on all the images.
As we have seen we are hitting issues#2327 a lot of times with this,
we start to leave a lot of stale images. Currently, we rely on
`--extra-create-metadata=true` to decide to set the metadata or not,
we cannot set this option to false to disable setting metadata because we
use this for encryption too.
This changes is to provide an option to disable setting the image
metadata when starting cephcsi.

Kubernetes 1.24 and newer use a different path for staging the volume.
That means the CSI-driver is requested to mount the volume at an other
location, compared to previous versions of Kubernetes. CSI-drivers
implementing the volumeHealer, must receive the correct path, otherwise
