Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Update results printed in configguide.rst

    It updates the entry points and all results.
    It also takes into account that:
      - juju_epc was added
      - fds was moved to features

    It should be noted that refstack_defcore, parser and several vnfs are
    failing from the time being.
