Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Fix 2 issues related to logger in pytest_suite_runer.py"
  - Fix 2 issues related to logger in pytest_suite_runer.py

    logging.ini requires the full name otherwise all log messages are lost.
    Calling basicConfig() is useless as it has been correctly configured by
    run_tests.py before.
