Proposal to combine HSDir and IP in next-gen hidden services

Description

This ticket exists to track the scheme[1] to remove HSDirs along with proposal 224, by combining their behavior with the introduction point.

The broad overview is that the client would choose an IP using the same algorithm proposed for choosing a HSDir, build a circuit, and ask for a "descriptor" containing metadata and the IP encryption key. The client then sends INTRODUCE1 over the same circuit, and from there proceeds as already proposed.

See the tor-dev thread for some prior discussion on the tradeoffs. I have tasked myself with writing some real text for this based on proposal 224.

I've done some work on combining HSDirs and IPs for the one-ion / direct onion services project (client-only anonymity). This is in addition to shorter onion service paths to HSDirs, IPs, and RPs.

We could either backport (well, back-design) this part of proposal 224 to the current HSDirs and IPs, or wait for proposal 224 to be active on the public Tor network.

Edit: I only speak for myself.

This ticket is not really useful to keep around. First, this has been written in proposal 246 and second it has been put in needs-research so closing the ticket.
