contextutil.RunWithTimeout gives error messages like:

operation "send-snapshot" timed out after 1h0m0s (took 10s): ‹rpc error: code = DeadlineExceeded desc = context deadline exceeded›

Where 1h0m0s is the timeout passed to RunWithTimeout(). However, this is misleading, because either the caller or callee can have set their own context timeout that is smaller than the timeout given to RunWithTimeout.

This is even worse in older releases, where the "(took 10s)" part is not present, leading readers to believe the operation actually took 1 hour.
