As part of T228380, MediaWiki metrics need to make it into Prometheus.
This task is complete when:
- MediaWiki is capable of exporting Prometheus-style metrics
- These metrics are consumed by the production Prometheus
- All MediaWiki metrics and module metrics are shipped in this manner
- All dashboards are updated to use these new metrics
- All previous code changes needed for this are merged and deployed in production.
