The Uyuni Helm chart files under `roles/uyuni/files/uyuni/server-helm/` have been removed from the repository as they are no longer needed in this deployment inventory. This change reflects a structural adjustment to externalize or re-architect the Helm chart management for Uyuni server deployments.
Added new playbook `setup_metrics_server.yml` and standalone role `roles/metrics_server/` to centralize Kubernetes metrics server deployment and configuration, separating concerns from the main uyuni role for modularity and reuse.
