Provide a way to configure the metrics exposed on <cluster-master>:9104/cluster-metrics

We use Prometheus to monitor out production in general and MemSQL as part of it.
This answer provided us a way to expose metrics about pipelines status and query throughput:

Monitoring SingleStore pipelines with Prometheus

Hello, Thank you for reaching out and welcome to our community! For pipeline errors and batches (e.g., anything from information_schema.pipelines_* tables) we don’t yet expose that in the exporter, but it’s on our roadmap and we plan to release it with the next major version of SingleStore. Our samples endpoint that you found exposes our mv_activities tables, which essentially is a sample of all activities running in the system as well as their respective resource usage (e.g., memory, disk, n…

It is great but returns enormous amount of metrics (50K) and might be overhead on both MemSQL and Prometheus.

It is relevant to MemSQL 7.3

Thanks,
