    Fix sphinx-docs job
    
    build-openstack-sphinx-docs jobs fail on all 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.
    
    This patch is necessary until the tox_install.sh removal [1] is merged in.

    Note: This commit includes the following unrelated changes
    to pass the gate.
    (Actually I2d125ce2251473f896fc251b8fa51cfa29721850 might not
    be necessary on this branch. But I included it as it was a part
    of the original commit on master.)
    ----------------------------------------
    Disable failing style checks (W503, E402) for now.
    
    I (yamamoto) guess they are new with pycodestyle 2.4.0.

    ----------------------------------------
    Update UPPER_CONSTRAINTS_FILE for stable/queens
    
    The new stable upper-constraints file is only available
    after the openstack/requirements repository is branched.
    This will happen around the RC1 timeframe.
    
    Recheck and merge this change once the requirements
    repository has been branched.
    
    The CI system will work with this patch before the requirements
    repository is branched because zuul configues the job to run
    with a local copy of the file and defaults to the master branch.
    However, accepting the patch will break the test configuration
    on developers' local systems, so please wait until after the
    requirements repository is branched to merge the patch.

    Port rally plugins to use proper modules
    
    Sometime ago, all OpenStack related stuff moved from the main repository
    to the separate one - https://github.com/openstack/rally-openstack .
    All further development and maintance will be done only in a new
    repository. As for first major release, the structure is not changed, so
    only imports should be changed.

    ----------------------------------------
    Add dummy docstrings to avoid Sphinx 1.7.x warnings
    
    We need to workaround this locally because:
    - It's unclear how long os-vif patch [1] will take
      to be merged.
    - While Neutron patch [2] has been merged, docs build on
      gate is using released versions of dependencies.
    
    The idea was taken from keystone. [3]
