    Fix check, gate and periodic jobs

    This is a combination of 3 commits:

    1. Fix sphinx-docs job for stable branch

    build-openstack-sphinx-docs jobs fail on stable branches due to the new
    pip version 10 introduces some previously Warning as Error: in case of
    calling "pip install" without any package name, the command fails.
    tox_install.sh is called during docs job without any package passed to
    pip.

    Also some tests still needs networking-odl package to be installed, however
    it is removed from the required-projects of networking-bgpvpn, so they
    fails now. To fix this, the easiest solution is to add networking-odl
    to .zuul.yaml on stable/* branch as required project.

    2. Add networking-odl for periodic-stable jobs

    periodic-stable jobs fail: networking-odl is required for jobs on queens
    and older stable branches. From rocky, there is no tox_install.sh any
    more, so this is not needed there.

    3. Fix post gate hook to accommodate for new os-testr

    New os-testr uses stestr under the hood, which creates .stestr but not
    .testrepository directory in the current dir. Other than that, it
    doesn't seem like there is any difference in the format or names of
    files generated in the directory.

    This change also wraps up another fix (simultaneous voting test job
    breakage) related to a recent change in the neutron repository of
    the import statements for ml2 config.
