Title:
  fake rpc driver should raise timeout exception if no consumers
  registered

Status in OpenStack Compute (Nova):
  Fix Released
Status in Oslo - a Library of Common OpenStack Code:
  Fix Released

Bug description:
  Seen here: https://review.openstack.org/3274

  If you do a call() with a real driver and no consumer responds, you
  get a timeout exception

  The fake driver should implement these semantics too. The patch is
  simple e.g.

        try:
            consumer = CONSUMERS[topic][0]
        except (KeyError, IndexError):
   -        return iter([None])
   +        raise rpc_common.Timeout()

  but Nova's unit tests break massively with this change, so they'd need
  to be fixed first

  The oslo.messaging fake driver already does the right thing.
