object Metrics

Client middleware to record metrics for the http4s client.

This middleware will record: - Number of active requests - Time duration to receive the response headers - Time duration to process the whole response body - Time duration of errors, timeouts and other abnormal terminations

This middleware can be extended to support any metrics ecosystem by implementing the org.http4s.metrics.MetricsOps type
