Update git submodules

Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Modify TestCase constructor attributes

    Every feature/testcase now allows receiving the data defined in
    testcases.yaml as args (name is renamed to case_name).

    From the time being, only project and case names are handled. Next
    pending patches will add criteria, cmd and repo to this list.

    It keeps the default values for case names except for features which
    will be aggregated into Feature.
