Title:
  Use auto-deleted queues prevent rpc flood

Status in OpenStack Neutron (virtual network service):
  Won't Fix

Bug description:
  Currently we use 'call' instead of 'cast' for prevent rpc flood. But
  'call' doesn't scale(https://docs.google.com/file/d/0B-
  droFdkDaVhVzhsN3RKRlFLODQ/edit).

  The flood reason was all the agents send message to the queue, but
  without quantum server, all the message will buffered in the queue.
  After quantum server startup, all the messages that buffered in queue
  will flood quantum server.

  We can set the queue as auto_delete. After quantum-server stopped, the
  queue will be deleted automatically. Messages that sent by agent will
  be dropped. Then the agent won't flood the quantum-server when it
  startup.
