### API Change

- Add auth API to get self subject attributes (new selfsubjectreviews API is added). 
  The corresponding command for kubctl is provided - `kubectl auth whoami`. ([#111333](https://github.com/kubernetes/kubernetes/pull/111333), [@nabokihms](https://github.com/nabokihms)) [SIG API Machinery, Auth, CLI and Testing]
