I'm not sure this is really going to end up moving things forward.

I think we should just write to the build farm owners, we plan to drop
python2 support in, say, 60 days, please update your setup to use
python3 or disable python support.

If we add this test first, then all we're going to learn is probably
that 60% of those who are currently using python2 don't have python3
installed, and then we're still going to have to send that above email.
