Fix JUnit Test for ControlLoops

Fix JUnit Test for ControlLoops

Fixed the test case by using getters and setters for Policy objects
in the drl. Added gson dependency in the pom to fix gson runtime errors.

Fixed dependencies in template.demo pom to add vfc.

The drl was having compilation errors in the guard permitted
rule due to the operation request object not being casted
into a VFCRequest when being passed into the VFCManager.
