Update git submodules

Update git submodules

* Update docs/submodules/releng from branch 'master'
  - armband-deploy.sh: sudo ci/deploy.sh

    New MCP deploy scripts have a hard requirement on running as root.
    Bring back sudo for the `ci/deploy.sh` invocation, aligning with
    Fuel@OPNFV.

    NOTE: This can be later avoided/reverted if we can guarantee the
    "jenkins" user has sudo rights, even without a tty present.
