Would add a line above explaining what this list represents or shows. I would assume it's something like "Products metrics covered by the ServiceMonitors below - Metrics origin(?)"

This matches two services probably, each of the Kafka Pods are scraped twice
| # [x] NiFi 1 - native | ||
| # [x] NiFi 2 - native | ||
| # [ ] OpenSearch - not officially part of the platform yet | ||
| # [ ] Spark - native - was too lazy, no idea if we even expose metrics |

This is a somewhat big PR, the monitoring stack rotted a bit over the last years and things broke.
This PR cleans everything up and achieves a better state than ever before :)
I now also took the time to look into ServiceMonitors and how they work, so we are able to scrape a lot more of products than before!
