Rajat Dhasmana ae22195df7 Fix reimage with snapshot backed image

When we create a snapshot of a server that is volume-backed,
glance creates a zero sized metadata entry of the image which
is backed by the volume snapshot.
When we try to reimage a volume with that given image, we need
to fetch the volume snapshot details from the image metadata.
Now to reimage, we need to create a new volume from snapshot and
copy the data from our snapshot-volume to our original volume
for which we use the generic revert to snapshot mechanism as
it performs the same steps.
