Additional BusinessRuleTask support that allows to decouple rules from processes - as default BusinessRuleTask uses exact same working memory (kie session) as process which essentially means same kbase. To allow better separation and maintainability BusinessRuleTaskHandler is provided that supports:- DRL stateful
- DRL stateless
Session type can be given by KieSessionType data input and session name can be given as KieSessionName property -these apply to DRL only.
Results returned will be then put back into the data outputs.
DRL handling is based on same names for data input and output as that is then used as correlation.
