After some investigation, we don't actually need to this for the M/R project so I'm closing for now (though it would be nice to refactor some of these helpers). At least for the replica set case, the M/R translation can use the MongoProcessInterface to attach a cursor source and get a runnable pipeline. Some work may be needed on mongos to take advantage of $exchange, but that will be tracked in a separate ticket.
