 With probability of choosing path selection from consensus, we could guess
 and build preemptively inter-relay connections.

 If we cannot simple preconnect orcon to any node. May something like this
 could still benefit in lower latency after bootstrapping. for very
 uptodate nodes and nonstable.

 Exit: build preemptively inter-relay connections to middle (non guard
 flag, non exit flag) but low probability of connection coming from guard
 directly (guard have low middle  probability)
 Guard: build preemptively inter-relay connections to suspected middle
 relays
 Middle:  build preemptively inter-relay connections to approximately
 anything?

 The idea is of having benefits from the way of clients do build circuits
 preemptively. Guess it, build it and leave it open in idle state for
 future use without building on the fly without TCP/tls rtt.
