Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Leverage on pbr (Python Build Reasonableness)"
  - Leverage on pbr (Python Build Reasonableness)
    
    pbr can inject requirements into the install_requires, tests_require
    and/or dependency_links arguments to setup. They were previously
    falsy unset.
    
    It also supports conditional dependencies which can be added to the
    requirements (e.g. subprocess32; python_version=='2.7').
    Then requirements.py3.txt is removed.
    
    It also removes functest/cli/setup.py which seems false and obsolete.
    
    Dockerfile is updated as well. One temporarily link is created because
    of several hardcoded paths in Functest.
