Optimized Resource Usage for Observability Platform

[Rotfuks]

Motivation

we aim to have minimal resource usage for our observability platform in the clusters of our customers. In a best case scenario they don't realise our tools are running there and they lead to no additional cost. This is not really possible, but we can reduce the impact. Here's a list of tickets we collected to improve the overall resource consumption of our systems.
