My understanding is that it was mainly being used so we could have sane testing on py26. With py26 support being dropped, we no longer need it. Also drop discover from test-requirements.txt, as we don't seem to actually use it. Change-Id: Iee04c42890596d3b483c1473169480a3ae19aac8 Related-Change: I37116731db11449d0c374a6a83a3a43789a19d5f
