Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "xci: Configure daily job to use xci scripts"
  - xci: Configure daily job to use xci scripts

    Daily jobs are now switched to using xci-deploy.sh script together
    with the environment variables, playbooks, and so on.

    These jobs do not set any version for any of the component as
    the point with these jobs is to test the platform itself, not the
    tools.

    DIB related stuff is still left as parameters to deploy job for SUSE
    and CentOS jobs so we can override what is set by xci depending
    on the distro.
