Update git submodules

* Update docs/submodules/integration/test from branch 'master'
  to e70b662451a3509deda2f888effa5de9f3abf6ac
  - Add ability/flag to clean OS in suite setup

    it will make it easier for other environments to adopt our
    upstream CSIT if we can also easily provide the ability to
    clean up the environment from any left overs that their
    previous tests may have left over.
