Bug 7533 : Fix for bind/unbind in DHCP service

- If the unbind is called from interface state listeners there could be
  chances of ending up in a race condition in service bind logic and hence
  the flow does not get removed.
- Moved the bind service call to interface config listener rather than state
  so that the service flows get programmed as soon as the interface is UP.
