LIU Yulong 00bf365025 [L3][QoS] Neutron server side router gateway IP QoS
This patch enables to bind a QoS policy to the router gateway,
then in L3 agent side SNAT traffic for the VMs without floating
IPs can be limited under the policy bandwidth rules. This is
suit for all kinds of L3 routers: DVR, DVR with SNAT HA, L3 HA
and Legacy.

API update router gateway json:
{
router": {
  "external_gateway_info": {
    ...
    "qos_policy_id": "policy-uuid"
    }
  }
}

A new attribute ``qos_policy_id`` is added to the L3 router
gateway.
* It enables users to associate QoS policies to L3 router gateways
to control the rate of transmission of the associated SNAT traffic.
* At the moment, only bandwidth limit rules are supported in the
QoS polices.
* To enable this feature, the ``qos`` service plugin has to be
configured in the Neutron server and the ``gateway_ip_qos``
extension has to be configured in the L3 agents. Please refer to
the ``QoS`` section of the ``OpenStack Networking Guide`` for more
specific details.
