Add support for checkpoint image
This is an enhancement proposal for the checkpoint / restore feature of
Podman that enables container migration across multiple systems with
standard image distribution infrastructure.
A new option `--create-image <image>` has been added to the
`podman container checkpoint` command. This option tells Podman to
create a container image. This is a standard image with a single layer,
tar archive, that that contains all checkpoint files. This is similar to
the current approach with checkpoint `--export`/`--import`.
This image can be pushed to a container registry and pulled on a
different system. It can also be exported locally with `podman image
save` and inspected with `podman inspect`. Inspecting the image would
display additional information about the host and the versions of
Podman, criu, crun/runc, kernel, etc.
`podman container restore` has also been extended to support image
name or ID as input.
