Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Print OpenStack login information at the end

    The info is logged to the console before post-deployment tasks and
    this makes it seeing the deployment status and login info inconvenient.
    This change moves the logging to the end, after post-deployment.
