Public bug reported:

Now neutron L3 router gateway IP has no way to set QoS.

Description
===========
For floating IPs, it can be associated with QoS policy,
and TC rules according to QoS policy with bandwidth limit
rules will be installed in router namespace.

And, neutron can bind qos policy to the gateway port, but
such proposal is to limit the bandwitdh on L2 perspective.
When QoS is bound to the gateway port, all north-south
traffic is restricted. Such restriction is inflexible.

Therefore, we need to provide an alternative method in the view
of L3. Aka, allowing bind QoS to router gateway IP.

Proposed Change
===============
models:
QosPolicyRouterGatewayIPBinding

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