Add missing GCP quota metrics to Thanos/Mimir
We currently have monitoring in place for GCP quotas that are about to hit their limits, however, not all of our GCP projects are currently being monitored. If we were scraping metrics from all of our projects, we potentially could avoid running into issues like this.
There's a MR open against the gcp-quota-exporter project to allow scraping multiple projects from a single exporter. This is intended to allow us to monitor all of our projects without deploying an exporter for each one.
