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.

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.
