Add operator metrics endpoint with configurable mTLS via METRICS_SCHEME, METRICS_HOST, and METRICS_PORT env vars. The monitor controller creates a server cert, Service, and ServiceMonitor for Prometheus integration. Client auth trusts the tigera-ca-private CA rather than individual leaf certs. Includes a custom Prometheus collector for operator status gauges. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
