As referenced in issue #406, this update includes the following enhancements:

Flags for Deletion Operations: --delete-volumes: Deletes associated volumes when deleting a Kubernetes cluster. --keep-firewalls: Retains dependent firewalls during deletion. --keep-kubeconfig: Preserves Kubernetes configurations.

Additional Output and Messaging: Implemented the second part of the acceptance criteria: Alongside cluster deletion details, outputs information about remaining volumes. Provides an informational message on stderr, suggesting the --delete-volumes flag for future use.

Error Handling: Addressed potential error scenarios to ensure robust operation. Please review and let me know if any changes are needed.
