Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "Add functest return status in Alpines"
  - Add functest return status in Alpines
    
    So far we had 2 approaches:
    
     * return Functest CI status: can be OK even if tests are FAIL
     * return Functest Test status: can be FAIL even if all Functest tests are OK
     (Fail in onboaraded tests)
    
    A 3rd way is possible thanks to [1].
    We consider only Functest status and Functest tests for the return statement
    
    the return will be FAIL only if
    
     * error in the framework
     * error in Functest Tests
    
    So concretely, if promise, Doctor can be FAIL, if Functest tests are OK, the
    return will be PASS
