Comment:
This also came up in #24228, where we found that Tor was creating a new
circuit about every 6 seconds with this timeout.
The goal is to learn a circuit build timeout within 30 minutes, so that
unused orconn connections aren't padded by the netflow padidng for too
long while we learn this timeout (which wastes bandwidth for clients that
want less padding). In #24228, it looked like we may actually learn it
within 10. So we could make this default 3X slower.
I will look at this and work on a patch to change the default and make it
a consensus param.
