Support shimv2 (now a functional deficit vs. Docker)

[smithfred]

Feature request description

See #17070 for further details, which was locked as stale, so I can't comment there.

This functionality exists for Docker as of last year - see moby/moby#43887.

Additional context

Currently there's no way to run fully functional virtualisation-isolated containers under Podman, which this would allow, via Kata. Contrary to the last comments on the linked issue, krun is not a suitable alternative - for example, it does not support exec-ing into containers, and ignores container user/group directives, breaking the ability to run third-party container images that expect to be run as a specific user.

I don't think anything on our side has changed, we have no resources to maintain several different complex interfaces with other runtimes that are not CLI compatible with crun/runc.

You can always file enhancements or bug reports for krun. Also there is crun-vm as well https://github.com/containers/crun-vm/

I am going to close this as there has been no other comments here and I don't think our position has changed, this seems like more maintenance work then we can take currently.
