Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Use assertIn(x, y) instead of other variations"
  - Use assertIn(x, y) instead of other variations
    
    unittest.assertIn(x,y) should be used instead of:
    * unittest.assertTrue(x in y)
    * unittest.assertEqual(x in y, True)
    
    Also fixes pep8 violations existing in the file.
