    Update tox.ini to work with tox 4

    This change will allow this repo to pass zuul now
    that this has merged:
    https://review.opendev.org/c/zuul/zuul-jobs/+/866943

    Tox 4 deprecated whitelist_externals.
    Replace whitelist_externals with allowlist_externals

    Zuul is pinned to use tox < 4 in order for the py39
    unit tests to pass. Additional changes for skipsdist
    may be required in order to work properly with tox 4.
