[kube-prometheus-stack] kube-apiserver.rules is duplicate

[apricote]

Describe the bug a clear and concise description of what the bug is.

The kube-apiserver.rules rule group is duplicated by the kube-apiserver-burnrate.rules and kube-apiserver-histogram.rules rule groups.

In the upstream kubernetes-mixin, the kube-apiserver.rules were split into the other two in this commit: kubernetes-monitoring/kubernetes-mixin@2986c52

It looks like the two new files were added, but the old/deprecated file was not removed in #1165

This causes unnecessary CPU load in our kube-prometheus-stack installation. In total the rule evaluations take ~40seconds for each interval, of that kube-apiserver.rules takes 20seconds and -burnrate.rules + histogram.rules together take another 20seconds. By removing the old kube-apiserver.rules file, we could reduce or rule evalutions time by 50%.

What happened?

Duplicate rules for apiserver_request:burnrateXX and cluster_quantile:apiserver_request_duration_seconds:histogram_quantile are deployed in the default configuration.

What you expected to happen?

I expected no duplicate rules to be deployed.

How to reproduce it?

Deploy the default chart and observe the duplicated rules in prometheus.

Enter the changed values of values.yaml?

NONE
