CoraidDriver: create_volume_from_snapshot of a different size

[Jean-Baptiste RANSY]

When you create a Volume from a Snapshot, the 'size' argument for the new volume isn't used at all
So, the new volume created will be created (successfully but) with the same size as the snapshot size.

Cinder think the volume has been created with the right size.

We just need to call Coraid ESM LV Resize with the REST API after the volume has been created.
