run-tests: remove options from Test.__init__ All options are now passed as arguments and we no longer need options. This enables us to instantiate Test from "plain old data" types. Since options must be given as arguments, it also makes people think harder about adding things that may not belong in Test. This will help ensure a proper separation of responsibility going forward.
