Update git submodules

* Update docs/submodules/integration/test from branch 'master'
  to c2708f9c1052be0cf75a9299fb083661b09be059
  - Revert "Add new keywords in OpenStack robot file."

    the additional args given to the ssh rule create is
    broken. I almost asked to see this patch in the sandbox
    first, but thought that change was safe and a noop.

    This reverts commit a9365258a7049f8f29fc49ff6b136f9d0e99667d.
