This diff is part of https://github.com/ooni/probe/issues/1505. You will notice that I have not adapted all the (great) tests we had previously. They should live at another layer, and namely the one that deals with performing measurements. When I'm refactoring such a layer I'll ensure those tests that I have not adapted here are reintroduced into the tree.
