Removed unfunctional test in service `users`
Enabled up/down-scaling of the services * Changed the default-port of the services, so that all services can be started local in parallel * The queriable Kafka-Streams-Apps derive their local address automatically, so that they can be scaled up/down in Docker-Compose * Added traefik as reverse-proxy to the setup
Simplified & unified the endpoint-paths
Users are materialized as KTable
Query-results are enriched with user-data
