Add ability to run tests on specific commit


We were trying to track down a broken build and it turned out to be one of 6 commits that were pushed at the same time. The tests weren’t failing on our desktops, so we wanted to be able to run tests against each commit to see which one introduced the bug.

It didn’t seem like there was any way to do this, so I made a new branch and pushed each commit one by one to force them all to be rerun. It would be great if there was an easier way to do this in the UI.
