August 10th 2023 - Proto_handler update

Fix the proto_handler to separate request handling from input handling
Make the proto_handler just pass messages between. We don't need to actually process anything
Add some logic to determine if the request is coming from the orchestrator or consumer
Some other various proto_handler fixes
