Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Remove logger_test_results"
  - Remove logger_test_results

    It was only called in Feature which the result is already printed
    (see __str__()).

    It also eases moving Feature to xtesting as it breaks the link to
    functest_utils.
