Refactor noble cluster configurations by removing deprecated Argo CD application management files and transitioning to a streamlined Ansible-driven installation approach. Update kustomization.yaml files to reflect the new structure, ensuring clarity on resource management. Introduce new namespaces and configurations for cert-manager, external-secrets, and logging components, enhancing the overall deployment process. Add detailed README.md documentation for each component to guide users through the setup and management of the noble lab environment.
