Remove PDP from all active groups
The code to disable a PDP used the group name, extracted from a prior PdpUpdate request, to identify the group from which the PDP should be removed. This is not sufficient, as the requests tracker may have never seen an update request. Therefore, the code was modified to simply remove the PDP from all active groups. Also made removeFromGroups(pdpName) public so that it can be used by other PAP code. Change-Id: Iedec88cb23e586944563dcc5ac82ff3b9f122f8c Issue-ID: POLICY-1542 Signed-off-by: Jim Hahn <jrh3@att.com>
