Update git submodules

Update git submodules

* Update docs/submodules/auto from branch 'master'
  - May 15th update (identity, router gateway, options, summary)

    JIRA: AUTO-38

    Automated configuration of an OpenStack instance for ONAP

    Updates:
    - using identity proxy now works
    - attaching a gateway to a router now works (at router creation)
    - added --debug and --delete options
    - added summary display at the end, with network IDs (for YAML files)

    Not yet working:
    - existence tests and deletions, waiting on OS-SDK bug fix
      (equality test in Resource.py)
    - assigning user to project using SDK identity proxy
      (no such method yet in SDK identity proxy)
