Grafana display for Attended Sysupgrade

@aparcar The Grafana display for ASU seems to be timing out before it can return results:

Only the Cache Hits and Request per Client appear - the others show a spinner and then timeout

Yes I think I'm using too many labels for Prometheus to create the graphs, I'll simplify the stats a bit in the future. Maybe a simple CVS is actually enough...?

Sure. A CVS-style listing would be fine.

And is caching available? Computing the reports once per hour (say) would be plenty to tell me what I wanted to know. Thanks!

PS This is worth 10-20 minutes of your valuable time - no more, in my opinion. The data is titillating, but I don't believe it's important for operations.
