Public bug reported:

It appears that there are still places in Nova that are being hardcoded
to use the Cinder V1 api.  Evidence of this can be seen by setting
enable_v1_api to false in Cinder and then trying to use any of the 'nova
volume' commands.  Errors like the following are produced:

Cinder has  added version discovery in Liberty so Nova should go back to
using the 'volume' service type as the volumev2 service type will go
away and version discovery should take care of making sure the right API
version is used.
