Filter by 'created_at' return 500

[Hongbin Lu]

Neutron server will return 500 if we try to list ports with 'created_at' as filter. For example:

  $ curl -g -i -X GET -H "X-Auth-Token: $TOKEN" "http://10.0.0.19:9696/v2.0/ports?created_at=test"
  HTTP/1.1 500 Internal Server Error
  Content-Type: application/json
  Content-Length: 150
  X-Openstack-Request-Id: req-78d586d8-2ad1-4303-89e9-e93ffe4229cb

  {"NeutronError": {"message": "Request Failed: internal server error while processing your request.", "type": "HTTPInternalServerError", "detail": ""}}

IMO, the neutron server should return a 4xx error in this case.
