Update git submodules

* Update docs/submodules/functest from branch 'stable/euphrates'
  - Merge "Return Functest status to Jenkins" into stable/euphrates
  - Return Functest status to Jenkins

    It avoids mixing Functest and Features CI issues by simply exiting the
    status of Functest testcases. The result of third-party testcases are
    printed into console but are no longer taken into account into the
    global status.
