Migrate to an micro-service architecture

[jlndk]

To achieve much greater performance and scalability we should keep the current backend and the future frontend (#10) seperate.

My proposal is to convert this laravel project to lumen, since we really only need one route.

Additionally we would house the frontend in a seperate folder, where we have the freedom to plan out the app however we want.

To tie these two services together we could extend the current docker-compose file to have a separate image and container for the front and backend
