Is your feature request related to a problem? Please describe.
We over-rely on our built-in AdminUI. Production users are supposed to use Prometheus or one of its siblings (Graphite, etc). But - we have no good dashboards to give them other than what CC uses at any given point in time (and that we don't distributed proactively).
This makes for a poor story.

Describe the solution you'd like

We should use the catalog:

to auto-generate Grafana dashboards.

Describe alternatives you've considered
I don't see an obvious better alternative. We can continue doing little, but it seems sub par.

Additional context
Lots of great synergy here with #46103, which also relies on Grafana. We look at timeseries quite a lot during debugging, and I'm sure this would see use and would help us dog food the catalog's organization to make sure it's helpful.
