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.
