Update git submodules

* Update docs/submodules/functest from branch 'master'
  - Disable urllib3 warnings

    1. When running in compass OSA, lots of SubjectAltNameWarnings are
       shown in console, so just disable the warnings here.
       See https://github.com/shazow/urllib3/issues/497 for details
    2. Redirect warnings issued by the warnings module to the logging system
       via logging.captureWarnings(True)
    3. But urllib3 warning is still there for two cmds about rally/tempest.
