Improve Kubernetes adoption experience for youki

Description

I would like to make youki easier to adopt and test on Kubernetes.

Currently, it is possible to use youki with Kubernetes through containerd / CRI-O runtime configuration and RuntimeClass, but the setup still requires several manual steps. This can make it difficult for users to try youki on a Kubernetes cluster, especially for local testing environments such as kind.

This issue tracks possible improvements to make the Kubernetes adoption path smoother.

Possible work items

Some possible improvements include:

• Add a kata-deploy like DaemonSet for installing youki on Kubernetes nodes
  • https://github.com/kata-containers/kata-containers/tree/main/tools/packaging/kata-deploy
• Provide a documented kind-based test environment
• Document containerd configuration for youki
• Document CRI-O configuration for youki
• etc...
