Revert "Remove use of conduit Producer and Consumer."

Browse source 
This reverts commit 5f04dc6a23.

Leave the use of Producer and Consumer for now until we drop support for conduit-1.2.*.
conduit-1.3 introduces ConduitT and deprecates the use of type synonyms.
However, ConduitT is not present in conduit-1.2.
