Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Return pylint status code for modules rated 10/10

    It ensures that no pylint errors or warnings can be introduced by a
    new change. The first pylint call (to report issues) will be safely
    removed when all pylint errors and warnings are fixed in functest.
