Add optional TLS support for the operator metrics server (port 8080) to enhance security when exposing Prometheus metrics. The feature is opt-in and controlled entirely by the METRICS_CERT_DIR environment variable. When set, the operator will: - Enable TLS (SecureServing) for the metrics server - Look for certificates at the specified path - Use standard Kubernetes TLS secret naming (tls.crt/tls.key) When METRICS_CERT_DIR is not set (default), the metrics server continues to operate without TLS, ensuring no breaking changes to existing deployments. Usage: 1. Create a Kubernetes secret with TLS certificates (tls.crt and tls.key) 2. Mount the secret to the operator pod (e.g., /run/secrets/cnpg.io/metrics) 3. Set METRICS_CERT_DIR environment variable to the mount path 4. Update monitoring configuration (e.g., PodMonitor) to use HTTPS Signed-off-by: Armando Ruocco <armando.ruocco@enterprisedb.com>
