Issue XD-2738: Add arbitrary "side channels" to track module progress
As a user, I'd like to have an optional arbitrary "side channels" created so that when creating a module channels other than the primary stream channels (input, output) could be added to the bus (i.e. creating a tap channel *within* a flow). The optional "side channels" can be used to trace/track module progress.
