 This is important when we add a new chutney feature or network (like in
 #20069), then make Tor depend on it.

 One way we could do this is to check the exit status of chutney in
 chutney/chutney, and logging the appropriate message if it fails.

 Another way is for the Tor chutney tests to set CHUTNEY_MIN_VERSION, and
 then chutney warns if it's not that version. This would actually require
 us to version chutney.
