Update git submodules

* Update docs/submodules/sfc from branch 'master'
  - Merge "Conform SFC test to Functest framework"
  - Conform SFC test to Functest framework

    - Inherit from OSGCTestCase which takes care of pushing
      the result to the DB automatiically.
    - Functest will just need to import this module
      in testcases.yaml and the framework will launch it
    - It is still possible to call this script from python
      command line directly as it has a main function.
