Prometheus Metrics Scraping

This chart provides automatic Prometheus metrics scraping configuration through annotations. To enable metrics scraping for your service:

metrics:
  enabled: true
  path: "/metrics"  # Optional: defaults to /metrics
  port: "8080"      # Optional: if not specified, uses the first service port

When enabled, these annotations (prometheus.io/scrape: "true", prometheus.io/path, and prometheus.io/port) will be automatically added to your pods, making them discoverable by Prometheus.
