    Add "qos_policy_id" field to "Router" OVO

    This new synthetic field is linked to a
    "QosRouterGatewayIPPolicyBinding" register. This binding register will
    bind a QoS policy and a Router. Now is possible to provide this field
    in the create/update input parameters. If provided, the "Router" OVO will
    create/delete the "QosRouterGatewayIPPolicyBinding" register.

    The "Router" OVO takes this parameter from the DB object. When the DB
    object is retrieved, the QoS policy binding register is retrieved too
    due to a backref link in the "QosRouterGatewayIPPolicyBinding" DB model to
    the "Router" DB model.
