Why does Grafana even get involved? This seems unreasonable. Query from Grafana should go to Prometheus.
And if Prometheus needs to scrape metrics from BanyanDB, please do via BanyanDB Prometheus endpoint directly.
There is no point to propagate and store metrics in two places.

Got it. Metrics will be scraped by Prometheus from BanyanDB, and Grafana will only be used for visualization by querying Prometheus.
…cessary parameters. Update trace initialization to support new trace group functionality and enhance test cases with additional spans for better coverage. (apache#773)
