Gorka Eguileor b77fb72aa9 Change snapshots type with volume retype

Both volumes and snapshots have a volume_type_id field in the DB, but
when we migrate a volume we leave the snapshots with the old type.  This
can only happen for retypes that don't do migration, since we cannot do
a retype with migration if the volume has snapshots.

Leaving the snapshots with the old time makes a mess of the quota usage
when we do the retype as well as when we delete the snapshots.

This patch fixes the quota issue by making sure the snapshots are
retyped as well.  This means that we will check quotas for the snapshots
when retyping a volume that have them and we will properly reserve and
set the quota on retype.

     `Bug #1877164 <https://bugs.launchpad.net/cinder/+bug/1877164>`_: Fix
     retyping volume with snapshots leaves the snapshots with the old type,
     making the quotas wrong inmediately for snapshots, and breaking them even
     more after those snapshots are deleted.
