Update git submodules

Update git submodules

* Update docs/submodules/auto from branch 'master'
  - Merge "update of config script using new release of OpenStack SDK"
  - update of config script using new release of OpenStack SDK

    JIRA: AUTO-38

    - Issues in OpenStack SDK 0.13 were fixed in new release 0.14
    - revisited the script, made some changes (delete interfaces before
      deleting router)
    - Script now fully works: creates all objects, and can be used also
      for deleting (in a clean-up job for example)
    - resilient to re-runs: can attempt to re-create, won't crash if
      objects already exist (existence tests work, thanks to SDK 0.14
      fix). Likewise, can attempt to re-delete (no crash).

    - next steps will be:
      * update created objects based on ONAP-B requirements
        (current: still from Amsterdam; should be quite similar)
      * script to ensure Python3 and SDK are installed, and to
        ensure files are there (clouds.yaml, .img)
      * chain in CI pipeline: Fuel/MCP install, and this script

    Patch 2:
    made changes to address the comments
    - fixed the summary (works in any execution case), tested on hpe12
    - researched the URL support (use image proxy), but did not try yet
    (need to merge this for 6.2)
