Madhu Rajanna 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.
