Move message_queue over to deduplication via intents

Browse Source 
Due to each service having multiple distinct clocks, we can't expect a stable
ordering except the ordering an intact message-queue provides. The messages
emitted should be consistent however, solely with unknown order, which is why
we can craft intents based on their contents (already implemented by
processor-messages).
