0f724480f5 cephfs: implement DeleteVolumeGroupSnapshot RPC
implemented DeleteVolumeGroupSnapshot RPC which
does below operations

* Basic request validation
* Get the snapshotId's and volumeId's
mapping reserved for the UUID
* Delete snapshot and remove its mapping
from the omap
* Repeat above steps until all the mapping
are removed
* Remove the reserved uuid from the omap
* Reset the filesystem quiesce, This might be
required as cephfs doesnt provide any options to
remove the quiesce, if we get any request with same
ID again we can reuse the quiesce API for same set-id
* Return success if the received error is
Pool not found or key not found.

df770e4139 cephfs: implement CreateVolumeGroupSnapshot RPC
implemented CreateVolumeGroupSnapshot RPC which
does below operations

* Basic request validation
* Reserve the UUID for the group name
* Quiesce the filesystem for all the subvolumes
from the input volumeId's
* Take the snapshot for all the input volumeId's
* Add the mapping between volumeId's and snapshot
Id's in omap
* Release the quiesce for the filesystem for
all the subvolumes from the input volumeId's

Undo all the operations if anything fails.

991343d9e5 cleanup: do not pass EncodingVersion to GenerateVolID()
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.

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.

VolumeRequest is to create from a snapshot or volume
