The only encoding version that exists is `1`. There is no need to have
multiple constants for that version across different packages. Because
there is only one version, `GenerateVolID()` does not really require it,
and it can use a default version.
If there is a need in the future to support an other encoding version,
this can be revisited with a cleaner solution.

This commit makes use of crush location labels from node
labels to supply `crush_location` and `read_from_replica=localize`
options during mount. Using these options, cephfs
will be able to redirect reads to the closest OSD,

Implemented the capability to include kernel mount options and
fuse mount options for individual clusters within the ceph-csi-config
ConfigMap.This allows users to configure the kernel/fuse mount options
for each cluster separately. The mount options specified in the ConfigMap
will supersede those provided via command line arguments.

Add support to create RWX clone from the
ROX clone, in ceph no subvolume clone is
created when ROX clone is created from a
snapshot just a internal ref counter is
added. This PR allows creating a RWX clone
from a ROX clone which allows users to create
RW copy of PVC where cephcsi will identify
the snapshot created for the ROX volume and
creates a subvolume from the CephFS snapshot.

Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes.
This Pool parameter is optional and only used as 'pool-layout' parameter
during subvolume and subvolume clone create request in cephcsi
and not used for Snapshot-backed volume at all.
It is not saved anywhere for use in subsequent operations after create too.
Therefore, We can set it to empty and not error out.

We should not call ExpandVolume for the BackingSnapshot
subvolume as there wont be any real subvolume created for
it and even if we call it the ExpandVolume will fail
fail as there is no real subvolume exists.
This commits fixes by adjusting the `if` check to ensure
that ExpandVolume will only be called either the
VolumeRequest is to create from a snapshot or volume
and BackingSnapshot is not true.

CephFS does not have a concept of "free inodes", inodes get allocated
on-demand in the filesystem.
This confuses alerting managers that expect a (high) number of free
inodes, and warnings get produced if the number of free inodes is not
high enough. This causes alerts to always get reported for CephFS.
To prevent the false-positive alerts from happening, the
NodeGetVolumeStats procedure for CephFS (and CephNFS) will not contain
inodes in the reply anymore.
