FR/PR: gVisor/runsc-Support for Podman

[SlitEye]

It would be great if Podman supports officially gVisor (or runsc) as Runtime. gVisor works already with the Docker and Kubernetes runtimes. With official support in Podman, so that Podman pods could also be additional protected with gVisor.

Try it out and tell us what is broken.

Thanks for reaching out. Podman supports all runtimes implementing the OCI runtime specification, including gvisor. Note that gvisor requires root privileges, so I won't work as rootless podman (see google/gvisor#311).
