Share common knowledge on dashboard and rules analyse

[Nexucis]

Dear Mimir maintainer,

I have spent a couple of times on a new side project called metrics-usage. The goal of this project is to highlight which Prometheus metrics are used and where. (In which dashboard, in which Prometheus rules).

I have discovered that you are doing more or less the same thing and I took some inspirations from what you were doing for the Grafana dashboard.

Today I can assure you that the code you have to analyse the Grafana dashboards is incomplete and doesn't work very well. I have made a bunch of changes on my side to be more accurate and precise.

My question is simple: Would you be interested to import/reuse the code from metrics-usage to improve yours and ofc share knowledge and collaborate around this topic ?

If yes, then we can think about making an analyse library which can be imported in Mimir.

Well in case you would like to take a look to consider it, I have made a library https://github.com/perses/metrics-usage/blob/main/pkg/analyze/grafana/grafana.go. Should be easy to import now
