Comment 2 for bug 1801748

Since nothing is currently using the tox.ini in the repo, I've cleaned that up via the following commit. Sorry for the duplicate work, I didn't know about this branch.

There are some other useful sounding cleanups in Scott's branch worth looking at and applying before this bug is closable.

    Cleanup obsolete integration test code

    Prior to the introduction of git-ubuntu-self-test, bin/integration-test
    served as a testsuite runner, and tox was used for some style checks.
    These are no longer invoked in the jenkins runs[1,2] and thus are just
    vestigial now. In fact bin/integration-test no longer works since it
    calls `git-ubuntu` rather than `git ubuntu`; functionally it's just a
    smoke test like the one documented in the README.md already. To avoid
    future confusion, just drop these two old bits.
