Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Define Runner class"
  - Define Runner class

    It simply converts run_tests.py's functions to Runner's methods.
    This proposal could be enhanced in a second step to fully leverage on
    object programming.

    It defines as instance variables the former static variables to allow
    multiple runs (it's mandatory for unit testing).

    All false positives in unit tests are fixed but run_tests.py is still
    not fully covered.
