Code Issues Proposed changes

volume: Add 'volume attachment *' commands 

These mirror the 'cinder attachment-*' commands, with arguments copied
across essentially verbatim. The only significant departure is the
replacement of "tenant" terminology with "project".

  volume attachment create
  volume attachment delete
  volume attachment list
  volume attachment complete
  volume attachment set
  volume attachment show

Full support for filtering is deferred for now since that's a more
complicated change that requires additional commands be added first.
TODOs are included to this effect.
