Title:
  delete interface times out in check-tempest-dsvm-neutron

Status in Tempest:
  Invalid

Bug description:
  
  This occurred during a tempest run on https://review.openstack.org/#/c/78459/ (in Keystone). check-tempest-dsvm-neutron failed with a single test failure: tempest.api.compute.v3.servers.test_attach_interfaces.AttachInterfacesV3Test.test_create_list_show_delete_interfaces

  Looks like the test gets a token, starts booting an instance:

  POST http://127.0.0.1:5000/v2.0/tokens - Status: 200
  POST http://127.0.0.1:8774/v3/servers - Status: 202

  ... this is all probably expected... eventually it does a DELETE:

  2014-03-12 20:59:32,797 
  Request: DELETE http://127.0.0.1:8774/v3/servers/f4433c4f-4d27-492d-8794-77674a634c3f/os-attach-interfaces/f145579d-aaa5-4d44-941c-9856500f65b5
  Response Status: 202

  Then it starts requesting status... and eventually it gives up:

  2014-03-12 21:02:48,016
  GET http://127.0.0.1:8774/v3/servers/f4433c4f-4d27-492d-8794-77674a634c3f/os-attach-interfaces
  Response Status: 200
  Response Body: ... "port_state": "ACTIVE",  ... "port_state": "ACTIVE" ... "port_state": "ACTIVE"

  The test failed in _test_delete_interface:

  File "tempest/api/compute/v3/servers/test_attach_interfaces.py", line 127, in test_create_list_show_delete_interfaces
  File "tempest/api/compute/v3/servers/test_attach_interfaces.py", line 96, in _test_delete_interface
  Details: Failed to delete interface within the required time: 196 sec.

  The timings at the end show the slowpoke:

  tempest.api.compute.v3.servers.test_attach_interfaces.AttachInterfacesV3Test.test_create_list_show_delete_interfaces[gate,smoke]
  218.999

  ------------

  Neutron's last entry for the instance in q-svc.txt is

  [12/Mar/2014 21:02:52] "GET /v2.0/ports.json?device_id=f4433c4f-
  4d27-492d-8794-77674a634c3f HTTP/1.1" 200 1912 0.027403

  I grepped through the q-svc.txt log file and I don't see anyplace
  where the DELETE is forwarded on.

  --------

  Did the test not wait long enough for the operation to complete? Was
  the shutdown request ignored?
