Current implementation of the FlowControllerContainer does not expose
collectionProcessComplete(). Also, it appears that the ASB_impl never calls
CPC on the flow controller. Three changes are needed:
1) Add collectionProcessComplete() method to the FlowControllerContainer
2) Add getFlowControllerContainer() method to ASB interface. The ASB_impl
already supports this.
3) Modify collectionProcessComplete() method in AggregateAnalysisEngine_impl
to fetch FlowControllerContainer and delegate
collectionProcessComplete().
