    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.

    This commit includes the following unrelated change to
    pass the gate.
    ----------------------------------------
    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]
