    Handle ports assigned to routers without routerports
    
    In the case of having a port attached to a router but the routerport
    register is missing (as seen in the bug reported), this patch retrieves
    the full list of ports attached to a router, filtering by router ID
    and network ID or port ID. In case of having a port attached to this
    router with missing routerport register, a warning message is logged.

Title:
  Some ports assigned to routers don't have the correspondent routerport
  register

Status in neutron:
  Fix Released

Bug description:
  When running a few subnet detaching from router and deletion, some
  subnets are not possible to be deleted with this error:

  $ openstack subnet delete e81929f6-25ea-45c2-89b5-ff94afd7136a                                                                                        
  Failed to delete subnet with name or ID 'e81929f6-25ea-45c2-89b5-ff94afd7136a': ConflictException: 409: Client Error for url: http://10.0.0.104:9696/v2.0/subnets/e81929f6-25ea-45c2-89b5-ff94afd7136a, {"NeutronError": {"message": "Unable to complete operation on subnet e81929f6-25ea-45c2-89b5-ff94afd7136a: One or more ports have an IP allocation from this subnet.", "type": "SubnetInUse", "detail": ""}}
  1 of 1 subnets failed to delete.

  
  After checking the ports in that subnet, only the router_interface port is left behing (but in DOWN status):
  $ openstack subnet show e81929f6-25ea-45c2-89b5-ff94afd7136a

  Trying to detach that subnet from router does not return any error, but if run with '-vvv' the next appears:
  $  openstack -vvv router remove subnet 33114251-4771-490a-bd7b-10a51e017719 e81929f6-25ea-45c2-89b5-ff94afd7136a 2>&1 | grep "has no interface"       
  RESP BODY: {"NeutronError": {"message": "Router 33114251-4771-490a-bd7b-10a51e017719 has no interface on subnet e81929f6-25ea-45c2-89b5-ff94afd7136a", "type": "RouterInterfaceNotFoundForSubnet", "detail": ""}}

  And checking the database it is true that it is NOT there:
  MariaDB [ovs_neutron]> select * from routerports;
  +--------------------------------------+--------------------------------------+--------------------------+
  | router_id                            | port_id                              | port_type                |

  +--------------------------------------+--------------------------------------+--------------------------+

  However, by checking the router we get it is there:
  $ openstack router show 33114251-4771-490a-bd7b-10a51e017719 -c interfaces_info -f value | jq '.' | grep -C 3 10.128.8

    },
