(Docker-Compose) Deployed applications should be able to override the datasource configuraitons inherided from the Skipper or Dataflow servers

Currently, for the local deployment, the Spring datasource configuration of thg Dataflow/Skipper server is passed to the deployed applications as part of the environment context.

This affects only the maven/jar applications deployed in local mode.

Because the existing docker-compose configurations uses env. variables (e.g. SPRING_DATASOURCE_URL) instead of properties (like --spring.datasource.url) the deployed streaming apps are not able to configure customer per-app datasources.
