* 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
prior to this fix Grafana didnt delete meta data
about the provisioned dashboard in `dashboard_provisioning`
which means that the dashboard wasn't inserted into
Grafana again if the folder was delete within Grafana.
