modules/rocket: preliminary rocket module
This just stubs out a rocket meta module that renders with another module. Future commits will integrate GNU Rocket here. When recursive settings formally lands you'll be able to nest as much settings content as necessary for the underlying module used, as part of the rocket settings. That should enable describing stuff like complex compose scenarios for rocket to sequence.
