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.

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.

volumegroup.go holders all the helpers
to extra the group details from the request
and also to extra group details from the
groupID.
This also provide helpers to reserve group
for the request Name and also an undo function
incase if somethings goes wrong and we need to
cleanup the reserved omap entries.

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.

Padding a passphrase with null chars to arrive at a 32-byte length
later forces a user to also pass null chars via the term when
attempting to manually unlock a subvolume via the fscrypt cli tools.
This also had a side-effect of truncating any longer length passphrase
down to a shorter 32-byte length.

The `rbdGetDeviceList()` function uses two very similar types for
converting krbd and NBD device information from JSON. There is no need
to use this distinction, and callers of `rbdGetDeviceList()` should not
need to care about it either.
By introducing a `deviceInfo` interface with Get-functions, the
`rbdGetDeviceList()` function becomes a little simpler, with a clearly
defined API for the returned list.
