Comment (by arma):

 I have backed out the change, so it goes back to cbttestfreq=10, on moria1
 and in the dirauth-git.

 I'm sufficiently convinced that the overload is from onion service
 circuits, not from cbt testing circuits, and while reducing the cbt test
 frequency will indeed reduce overall load on the network, it does so
 exactly by messing up everybody's cbt estimate, which isn't worth it.
