Added support for 'Active' and 'Passive' states.
Removed the rest server start/stop from the Activator because the engine starts in PASSIVE state. Added code to start/stop the rest server when a pdp state change occurs. Issue-ID: POLICY-2154 Change-Id: Iec6fcc990dc3dde702a911eb4f90d29e25c395a2 Signed-off-by: Ali Hockla <ah999m@att.com>
