commit 42e31b5c45b5387d1c81067386373636bb8fd5c2
Author: Nick Mathewson <nickm at torproject.org>

Mark TestingEstimatedDescriptorPropagationTime as obsolete.
We stopped looking at this option in 85cf6dcba3693b, back when we
implemented the minimal pieces of prop275. Since then, we've had
code to validate and adjust this option, and to give it a different
value in testing networks, but the option hasn't actually done
anything.
We can safely mark it as OBSOLETE, since doing so does not make any
old configuration get rejected.
Closes ticket 32807.

+ o Removed features:
+ - The option "TestingEstimatedDescriptorPropagationTime" is now marked as
