Update PDP with null group/subgroup when disabled
Modified the code so that, when a PDP is unable to fulfill a request, an UPDATE is sent to the PDP with group=null and subgroup=null. Also made updates to eliminate group version due to changes in policy/models. Change-Id: I9400ef5f8c365f492113a5b592b9ee6b7218756e Issue-ID: POLICY-1542 Signed-off-by: Jim Hahn <jrh3@att.com>
