Prometheus Response Metrics support for GitLab Pages sites
We should look into support for monitoring GitLab Pages sites with Prometheus, and in particular supporting response metrics for individual sites.
I'm not quite sure how these are currently hosted (NGINX?), but this should be a completely integrated experience. We will need to think of how to display this best, especially when a single project may have actual applications deployed along with Pages site for documentation.
Longer term, people may use this as well for Business Metrics and A/B tests rather than just response metrics.
