Hello,
I was wondering if it would be possible to add the ability to configure the exported metrics, or exclude specified metrics, as in some cases I do not need the data from all of the high cardinality metrics and would prefer to exclude in the application instead of in the scrape config of Prometheus.
I took a peek, and it seemed possible in the collection registry, though my c++ is rusty.
If this is possible and makes sense to put in the lib vs. the consumers of the lib, and isn't planned, I can attempt a PR.

Thanks!
