MetricsOps algebra capable of recording Prometheus metrics

For example to following code would wrap a org.http4s.client.Client with a org.http4s.client.metrics.core.Metrics that records metrics to a given Metric Registry, classifying the metrics by HTTP method.

import org.http4s.client.metrics.core.Metrics
import org.http4s.client.metrics.prometheus.Prometheus

requestMethodClassifier = (r: Request[IO]) => Some(r.method.toString.toLowerCase)
val meteredClient = Metrics(Prometheus(registry, "client"), requestMethodClassifier)(client)
