volume: Add 'block storage cluster *' commands

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

  block storage cluster list
  block storage cluster set
  block storage cluster show

We used the 'block storage' terminology rather than simply 'volume' to
allow us to start distinguishing between the volume service and a volume
resource.
