- Kubeadm: `kubeadm upgrade node` now supports `addon` and `post-upgrade` phases. User can use `kubeadm upgrade node phase addon` to execute the addon upgrade, or use `kubeadm upgrade node --skip-phases addon` to skip the addon upgrade. Currently, the `post-upgrade` phase is no-op, and it is mainly used to handle some release specific post-upgrade tasks.

### Ztunnel Shutdown Implementation

The key to this "handoff" between Ztunnels is `SO_REUSEPORT`, which Ztunnel by default sets on all of its listeners.
This enables multiple processes with the same effective UID to bind to the same port (see `man 7 socket` for details).
Linux will then send new connections to one of the processes (first to accept wins, so effectively random).

This still requires delicate sequencing.

- Secure serving on port 10258 to cloud-controller-manager (configurable via `--secure-port`) is now enabled. Delegated authentication and authorization are to be configured using the same flags as for aggregated API servers. Without configuration, the secure port will only allow access to `/healthz`.
