Update git submodules

* Update docs/submodules/functest from branch 'stable/danube'
  - Revert "Make SFC test a python call to main()"
    
    This reverts commit d5820bef80ea4bdb871380dbfe41db12290fc5f8.
    
    Robot test runs before SFC test and it imports
    https://github.com/robotframework/SSHLibrary
    which does a monkey patching in 
    the python runtime / paramiko.
    Untill now sfc run in a new python process (clean)
    because it run using the bash command.
    But when importing it as a module and call main()
    from python, it will run in the patched runtime 
    and it will error out.
