dfo_gen is relying on dataflowapp.source_id, which is not in schema

[eflumerf]

dfo_gen needs the SourceID and token_count from each dataflow app. Before, the dataflow app configs were dicts, and daqconf_multiru_gen simply added a "source_id" member to that dict using the SourceIDBroker. Now that the dataflow app configs are schema dataflowapp objects, this is a potentially undefined operation. I have verified that appropriate configurations are still generated, but we need to re-think the logic here to make sure that we aren't relying on this kind of behavior.

Probably the resolution will involve restructuring the data sent to dfo_gen, but we don't want to do that right now because of other ongoing development (since it works for now).
