Draft: Load configuration via Quarkus, but just for a test function

This MR shows how the contants loaded via Quarkus. For test cases this works well. However, if this is used in theodolite, there may be problems as the loader must be injected.

Maybe interesting: https://stackoverflow.com/questions/69553028/how-to-read-quarkus-config-in-dedicated-kotlin-class

Closes #238
