Metrics
Server middleware to record metrics for the http4s server.
This middleware will record: - Number of active requests - Time duration to send the response headers - Time duration to send the whole response body - Time duration of errors and other abnormal terminations
This middleware can be extended to support any metrics ecosystem by implementing the org.http4s.metrics.MetricsOps type

A server middleware capable of recording metrics
Same as apply, but can classify requests effectually, e.g. performing side-effects. Failed attempt to classify the request (e.g. failing with F.raiseError) leads to not recording metrics for that request.
