    Use Tempest 'all' tox env

    Tempest recently moved tox default
    to py3 including all-plugin env.
    -https://review.opendev.org/#/c/703011/

    This will fail the py2 jobs which are using
    all-plugin tox env. Because tox all-plugin
    env var enable the sitepackages=True. Py2 jobs
    install the tempest plugins on py2 and all-plugin
    tox try to find the installed plugins on py3 which
    cause no test to run and fail the job.

    tox all-plugin has been deprecated since long and not
    supposed to use for plugins who already in migrated to
    separate repo in queens cycle.

    Using tox 'all' env to fix the issue.
