KEP-4033: Discover cgroup driver from CRI

https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/4033-group-driver-detection-over-cri#cri-api

• kubelet: get cgroup driver config from CRI kubernetes/kubernetes#118770

Requires CRI API 1.28

---

To try this, you need to enable the KubeletCgroupDriverFromCRI feature gate. (alpha: v1.28)

The end goal is to remove the cgroupDriver config from the kubelet, similar to pauseImage

According to the KEP, you use the brand new command to try it:

$ sudo crictl runtime-config
cgroup driver:   SYSTEMD

Once RuntimeService / RuntimeConfig has been implemented, that is.
