Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "bugfix: autoupdate failed due to mingle with watchdog"
  - bugfix: autoupdate failed due to mingle with watchdog
    
    1. In the original design, if the auto-job starts soon after
    the watchdog starts, the auto update might be mingled with
    connectivity check, which may lead to update failure. so instead,
    the connectivity is checked first, if failed and module is not in deploying,
    restart module.
    2. only automate-docker-deploy job will impact the container status during
    auto-job, so substitue auto-job status check with automate-docker-deploy's
    3. the watchdog is not only for testapi, but also for reporting, and
    all docker container server deployed in testresults.opnfv.org, so move it under
    utils/test/opts, which is leveraged to store tool-sets employed for testing tools.
