    Add explicit contextlib2 0.5<0.6 for queens ancient virtualenv

    As described in related bug we need to install a particular version
    of contextlib2 to fix an issue with very old virtualenv installed.
    Installing contextlib2 in this way seems to pull in a new enough
    version of virtualenv without causing other dependency issues.

    Also add tags: notest to skip molecule testing which makes
    tox-molecule job fail, ideally this task shouldn't run except queens
    release.
