Is your feature request related to a problem? Please describe.
If you want to operate an application you also want to monitor it. This doesn't only contains the readiness & liveness (e.g. k8s probes), this also contains to monitor metrics of the application like memory usage etc.

Describe the solution you'd like
One cloud native standard is to use prometheus based metrics scraping. To do this, we need one additional dependency and a small change in the application.yaml.
