XACML PDP DmaaP Deploy/UnDeploy Function
1. Added PDPUpdate listener 2. Added PDPUpdate Publisher 3. Added code to handle PdpUpdate messages and load policies being deployed 4. Modified Activator to register listener 5. Provided placeholder code to get policies from pdpx for return PdpStatus response to the PAP 6. Other minor modifications 7. Fix XacmlPdpApplicationManager to only load policy if supports policy type. 8. Checkstyle fixes 9. Updated applications to support loadPolicy(ToscaPolicy) and all the translators, JUnit tests. 10. Consolidated some duplicate code in the applications. Can probably do more in that area. 11. Fixed bug in Properties not really having a copy constructor. Change-Id: Ic29ad426061cbdb79c1339314667bb8ff8decb88 Issue-ID: POLICY-1451 Signed-off-by: Michael Mokry <michael.mokry@att.com> Signed-off-by: Pamela Dragosh <pdragosh@research.att.com>
