Further annotation for the springcloud genlet

[frademacher]

Thanks a lot for the issue @pelkmann. Can you elaborate a bit on which annotations you are going to add? In general, a good starting point are the already existing aspect handlers for the Genlet: https://github.com/SeelabFhdo/lemma/tree/main/code%20generators/de.fhdo.lemma.model_processing.code_generation.springcloud/src/main/kotlin/de/fhdo/lemma/model_processing/code_generation/springcloud/handlers/aspects with https://github.com/SeelabFhdo/lemma/blob/main/code%20generators/de.fhdo.lemma.model_processing.code_generation.springcloud/src/main/kotlin/de/fhdo/lemma/model_processing/code_generation/springcloud/handlers/aspects/ResponseEntityHandler.kt being an easy starter.
