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.
