Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Publish framework presentation"
  - Publish framework presentation

    This is the first version prepared before merging "Switch TestCase
    attribute criteria to result" [1].
    It will also be updated to integrate VNF classes as soon as they are
    ready (UT, pylint, docstrings...).
