Y-Axis-SI-scaling

[tilsche]

For metrics that use proper SI-Units, we could implement a Y-axis scaling to avoid exponential notation. I.e. instead of 5.000e+4 W, we use 50 kW.

I also thought about doing that in metricq-grafana, benefiting also other clients*, but that would be problematic in webview, because webview does metadata requests independent of data requests.

Pratically, this depends heavily on metricq/metricq-source-bacnet#3

*AFAIK grafana-metricq-datasource currently does not support using the metadata from the API.
