Refactor: update API endpoint interactions for principal management to improve parameter handling and request structure

- Modified the API endpoints for adding and renaming principals to align with new request models.
- Adjusted assertions in tests to reflect changes in the expected arguments for kadmin methods.
- Enhanced clarity by consolidating parameters in API requests.
