Xacml PDP Register/Unregister Changes

1) Modified activator
	- Extend and use ServiceManagerContainer
	- add topicSink and topicSource properties to TopicEndpoint
	manager
2) Added PAP registration class
3) Added PDP message formatting class
4) Added PDP State Change listener to listen for state change and send
back PDP Status.. then start heartbeat if not started already
5) Added Heartbeat publisher code to send heartbeat status on periodic
interval
6) UPDATE: Made changes to satisfy Jim's review comments
7) Added code to XacmlPdpApplicationManager to get supportedPolicyTypes
8) UPDATE: more changes to satisfy Jim's latest review comments
9) Fixed the failed Junits causing build failure
10) Made change to use NetworkUtil for getting PdpStatus name value per
Jorge's comment

Still need to in separate review:
1) Write Junits for new code

Registration and heartbeat flow as I understand it:
1) PDP starts and sends initial status to PAP with PASSIVE state
2) PDP listens for State Change from the PAP
3) PDP sends updated Active state to the AP
4) PDP begins sending periodic heartbeat status to the PAP
