Title:
  No port create notifications received for DHCP subnet creation nor
  router interface attach

Status in neutron:
  New
Status in OpenStack Search (Searchlight):
  New

Bug description:
  Creating a subnet with DHCP enabled either creates or updates a port
  with device_owner network:dhcp matching the network id to which the
  subnet belongs. While there is a notification received for the subnet
  creation, the port creation or update is implicit and has not
  necessarily taken place when the subnet creation event is received
  (and similarly we don't get a notification that the port has changed
  or been deleted when the subnet has DHCP disabled).

  My specific use case is that we're trying to index resource
  create/update/delete events for searchlight and we cannot track the
  network DHCP ports in the same way as we can ports created explicitly
  or as part of nova instance boots.

  The same problem exists for router interface:attach events, though
  with a difference that we do at least get a notification indicating
  the port id created. It would be nice if the ports created when
  attaching a router to a network also sent port.create notifications.

  Tested under mitaka RC-1 (or very close to) with 'messaging' as the
  notification driver.
