Update git submodules

Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Merge "Don't display functest report for single test cases"
  - Don't display functest report for single test cases

    When executing a single test case, it is not neccessary
    to show duplicated information about the result of the test
    case. The functest report only makes sense when running
    multiple tests.
    e.g. functest testcase run vping_ssh

    The report is still showed when doing:
         functest testcase run all
