Title:
  metadata agent is using python client to communicate with quantum
  server

Status in OpenStack Neutron (virtual network service):
  New

Bug description:
  dhcp agent, l3 agent and ovs, linux bridge agents are using AMQP message to communicate with quantum server,
  I think we should avoid using python client in metadata agent:
  def _get_instance_id(self, req):
          remote_address = req.headers.get('X-Forwarded-For')
          network_id = req.headers.get('X-Quantum-Network-ID')
          router_id = req.headers.get('X-Quantum-Router-ID')

          if network_id:
              networks = [network_id]
          else:
              internal_ports = self.qclient.list_ports(
                  device_id=router_id,
                  device_owner=DEVICE_OWNER_ROUTER_INTF)['ports']

              networks = [p['network_id'] for p in internal_ports]

          ports = self.qclient.list_ports(
              network_id=networks,
              fixed_ips=['ip_address=%s' % remote_address])['ports']
