Adding a StatefulKnowledgeSessionAware Interface

Interface to be implemented by any object that wishes to be notified of the

{@link org.drools.runtime.StatefulKnowledgeSession}

that it runs in.

Implementing this interface makes sense for example when an object requires access to session artifacts/details such as rule facts, sessionID, etc.

This interface can be implemented by a custom

{@link org.drools.process.instance.WorkItemHandler}

in case, for example, it needs to access a session to insert / retract some facts before proceeding further to the process node that fires rules ( groups, agendas, etc.. ).
