Title:
  Avoid extra query when loading qos queue binding

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  The nicira plugin supports the 'qos_queue' extension, and for this it
  performs an extra db query for each element being retrieved by the
  get_ports and get_networks operations.

  Using similar technicques adopted for other API extensions, this extra
  query, which negatively impacts performance and scalability, should be
  removed.

  This bug affects only the nicira plugin.
