PDPX Healthcheck/Statistic RESTful API entry point

Includes:
- Basic code structure modeled after policy distribution
- Code implementation to support Healthcheck/Statistics RESTful API entry point
- JUnits
- Fixed Checkstyles issues and added some missing statistics classes and
Junits
- Made changes per Jim's comments
- Made more changes per Jim's comments
	> made gson field static
	> using AssertThatThrownBy() mechanic from AssertJ
	> added setup and teardown to correctly terminate activator in
	Junit
- Made corrections to the statitics endpoint and junits
