Description
Based on multiple question on mailing list it appears that we need to have a general purpose processor to aggregate data (FlowFiles or content of FlowFiles etc). Basically provide an implementation of this http://www.enterpriseintegrationpatterns.com/patterns/messaging/Aggregator.html
Keep in mind that while MergeContent processor could be looked at as one of the variation of aggregation, the pattern and the problem has much more moving parts that need to be addressed (release, correlation, and aggregation strategies). So the new processor should be flexible enough to handle variety of aggregation use cases.
