Include returned attributes in Decision
Adds new method to return attributes in a decision, which can be configurable. By default it is turned off which ensures that the current functionality is maintained for our client applications. Enhanced the JUnits for the applications to ensure that no extra information is passed, thus maintaining backward compatibility. Issue-ID: POLICY-2865 Change-Id: Ia533e5462c0cb475cb1f72f34e95f128d6c52678 Signed-off-by: Pamela Dragosh <pd1248@att.com>
