add support for kata container runtime

[smira]

See https://github.com/kata-containers/kata-containers/blob/main/docs/install/container-manager/containerd/containerd-install.md

Currently blocked on kata-containers/kata-containers#927, as Talos is only cgroups v2.

Looks like the linked issue has been fixed. Would be great to see this implemented!

Kata containers binaries can be obtained from https://github.com/kata-containers/kata-containers/releases with the kata-static package (like https://github.com/kata-containers/kata-containers/releases/download/3.1.3/kata-static-3.1.3-x86_64.tar.xz),

Caution: This whole package is 2GB in size and would probably make the final SquashFS image large in size.

Another problem is that you can actually change the config of Kata Container (by default the path is /opt/kata/share/defaults/kata-containers/). Maybe we need to find somewhere to store those mutable config
