Cinder only supports uploading volumes of encrypted volume types as
images with disk format 'raw' and container format 'bare'. Screen
for this at the REST API layer when the request is made.
This change is applied directly to the VolumeActionsController in
the cinder.api.contrib module, so it affects both the Block Storage
API v2 and v3.
