Is there a way to exclude /metrics from the reporting

[gemcoder21]

Is there a way to exclude specific routes like metrics to exclude from the prometheus stats?

Not currently, no. I'd accept a PR to add a method to PrometheusMetrics to include/exclude routes, possibly based on a closure accepting a Request? It would probably require us to Box the closure which adds an allocation and pointer chase, but that's unlikely to be a huge issue.
