Expand to more UE4 worlds

[AOS55]

Begin to build several worlds so we move from a single world to multiple simulation configs follows from #20. Also understand how to interface with a UE4 container in a headless mode. This could be worlds for testing & training and then other worlds for validation only. Equivalent to simulating a never before seen environment (could be quite a different world from train & test) learn on a beach and field then validate in a mountain. Design a metod to test the containerization of this too.
