* Add new build info metrics that contains more info The goal was to add more information about Grafana. But rather than just adding those to the current metrics I created a new metric since its a common pattern in the prometheus community to expose that info in a metric named `*_build_info`. We keep the old metric to avoid introducing any breaking changes but we should be able to remove it the next breaking change
