Rename and reorganize scripts and configuration files for clarity. Updated `02_install_cert_manager.sh` to reference a new Helm values file for better configurability. Introduced nodeSelector and tolerations in `helm-values/cert-manager.yaml` for targeted deployment.
This commit includes Helm-based installation scripts for MetalLB, Traefik, Cert-Manager, and External DNS, along with their necessary configurations. Updates to cert-manager YAML ensure production-ready naming and namespace adjustments. These changes aim to streamline the deployment and management of Kubernetes services with simplified automation.
