Metrics collection middleware for HTTP requests

This middleware should be applied to all HTTP routes to collect comprehensive metrics for Prometheus. It tracks:

  • Total request counts (by method and status code)
  • Request duration (as histograms for percentile calculations)
  • In-flight requests
  • Error rates
