Fix more sonar issues in drools-applications

Addressed the following sonar issues:
- unused imports
- unused method parameters
- superfluous "throws" declaration
- fields within a serializable class must also be serializable; this
  was/will be fixed with a change to AaiCqResponse in policy-models
- use logger instead of System.out; turns out that the code that used
  System.out is no longer needed.  In fact, deleted several classes
  that are no longer needed: ControlLoopLogger and ControlLoopPublisher
- cyclomatic complexity and switch/case statements too big; used
  eclipse to extract chunks of code into separate methods
- duplicate code
  Note: extracted common code and used lambdas to eliminate duplicate
  code in PolicyGuardYamlToXacml.  However, a better approach would be
  to use object-oriented programming, using mini/nested objects to do
  the generation.  The lambdas would then become abstract methods.
  Nevertheless, that would entail significantly more re-write of this
  class than desired at this time
