Add RSOSIntroductionPoints feature
If a rendezvous single onion service chooses its own introduction points, and they are nearby, it gets better latency than choosing random introduction points.
There's a denial of service risk if they all go down, but RSOS has that risk anyway.
This is similar to the Tor2webRendezvousPoints feature.
