Downgrade or fix what is triggering some rendezvous circuit related warning in client log files
When you create a large number of concurrent rendezvous circuits (as a client connecting to an .onion) you see often in the log file:
[warn] Can't find any rendezvous circuit. Stopping
[warn] Unable to setup INTRODUCE1 data. The chosen rendezvous point is unusable. Closing circuit.
Since I can see no other bug related info surrounding these except #34083 (I've also run in debug mode) it seams like there's nothing the user can do about them, and it requires no action from user side and the user basically learns nothing from them. So, if they cannot be triggered by an actual bug or help us learn anything or discover a bug, maybe we should make them less alarming and downgrade the severity. If they are helpful for discovering other potential bugs, we should allow them. It's only occurring on heavily used clients.
