There is no need for the `Manager.DeleteVolumeGroup()` function as
`VolumeGroup.Delete()` should cover everything too.
By moving the `.Delete()` functionality of removing the group from the
journal to the shared `commonVolumeGroup` type, a volume group snaphot
can use it as well.

updated GetVolumeByID to return more
descriptive error so that caller no
need to add more details in
the error message.

It seems to be possible that the UUID was found, but the name is not
set. Checking on UUID makes the CreateVolumeGroup operation more
idempotent.

Add extra error checking to make sure trying to create an existing
volume group does not result in a failure. The same counts for deleting
a non-existing volume group, and adding/removing volumes to/from the
volume group.
