Comment 6 for bug 1173284

The reason for response status being 201 for create and 204 for delete is by the action_status dictionary in resource.py. The action for a "quantum router_interface_delete" command is "remove_router_interface". So adding a new definition to the action_status dictionary will allow router_interface_action to have a status of 204.

This is what I mean:
