Bugzilla

We will need to make sure:
 * tc-worker-runner README gets updated in `yarn generate` (and then no need to check `git diff` in its CI tasks, as the `yarn generate` task will catch it)
 * tc-worker-runner builds are built and included in the GitHub release
 * tc-worker-runner version needs to be updated to match taskcluster's version on release

And let's also rename it from `tools/taskcluster-worker-runner` to just `tools/worker-runner` :)

 * tc-worker-runner tests should run on windows, too, as in [.taskcluster.yml](https://github.com/taskcluster/taskcluster-worker-runner/blob/f67f687f4a27b6ef37315e7e1fb598de5b6d2549/.taskcluster.yml#L76-L113)
