[Relayminer][Follow-up] add forward capabilities to send request to suppliers

[eddyzags]

Summary

This PR aims to add capabilities to forward requests to HTTP and a WebSocket server in the relayminer.

It sets up a configurable authenticated endpoint (/services/{service_id}/forward) whose responsibility would be to forward raw requests from the Relay Server to the service ID (more precisely, service node or data node).

@jorgecuesta If you have some spare cycles, I'd really appreciate your thoughts/feedback/input on this feature!

I've personally done a few rounds of review on the previous implementation of this, but am looking for a Supplier's perspective in terms of the product/feature.

I can take a look on this into the weekend or Monday since I'm currently OOO right now.
