Update git submodules

* Update docs/submodules/domino from branch 'master'
  - Add domino package

    It's required by Functest to ease integrating all OPNFV projects and
    their requirements.

    It also synchronizes requirements with stable/ocata and renames
    domino-cli to domino_cli to conform with common module names.

    It defines scripts and console_scripts to rely on $PATH.
    run_multimode.sh is adapted to correctly call client, cli and server.

    It should be noted that run.sh can raise conflicts if it's already
    provided by another OPNFV package and that run_on_remote_nodes.sh is
    not fully updated. Otherwise it obliges all OPNFV installers to be
    updated as well.

    run.sh is unchanged and it's called by releng from local directory.

    It may rise runtime issues if several files are not loaded via
    pkg_resources.
