Update git submodules

* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: Add ability to pass command line options to xci-deploy.sh"
  - xci: Add ability to pass command line options to xci-deploy.sh

    We now support multiple PDF files so instead of introducing another
    env variable, we can simply pass this information as command line
    arguments to xci-deploy.sh. We can extend the script to allow more
    options line verbosity, scenario name, functest details etc so we
    can get rid of multiple env variables.
