Title:
  Delete the FloatingIP Agent Gateway Port only when External Network is
  deleted and also delete the port based on Agents decision.

Status in neutron:
  Fix Released

Bug description:
  FloatingIP Agent Gateway port is created on the nodes to substitute for the Gateway port, since gateway port is currently residing on the Network Node.
  So it makes sense for the server to delete the FloatingIP Agent Gateway Port only when the External Gateway Port is deleted for the Router.

  This would reduce the complexity in the Server side.

  We  should introduce an RPC call for the Floatingip Agent Gateway
  ports to be removed. The Agent should take necessary action to delete
  the FloatingIP Agent Gateway Port when the "last_fip_count" comes down
  to 1 in the agent.

  So this will be completely maintained by the agent.

  This would improve the control plane performance significantly for the
  Floatingip addition and deletion.
