Add "special" Operation classes for new usecases
Created place-holder for new "usecases" controller. Note: as of yet, this is still just a normal java project; it will be turned into a full-fledged kie-based controller in a later review. Added some Operation and a few other support classes that will be needed. Note: the detmTarget() method and it's various supporting methods, detmXxx(), found in GetTargetEntityOperation2 were cloned from the pre-existing ControlLoopOperationManager2 class, and modified to fit the strategy of the new controller. Likewise for the junit tests of those methods. Issue-ID: POLICY-2748 Change-Id: Idffa135a11a56bd6afdd2728706fd40168e80912 Signed-off-by: Jim Hahn <jrh3@att.com>
