Adapt to nova api 2.89 and skip some cinder calls

the 2.89 api version stopped returning 'id' field
for volume_attachments.

Use 'volumeId' instead, and skip resolving the volume name as
none of the code does use volume names, everything only
ever needs volume id, so we can safely skip some API requests.
