Add test case for container migration
The difference between container checkpoint/restore and container migration is that for migration the container which was checkpointed must not exist during restore. To simulate migration the container is remove ('podman rm -fa') before being restored. The migration test does following steps: * podman run * podman container checkpoint -l -e /tmp/checkpoint.tar.gz * podman rm -fa * podman container restore -i /tmp/checkpoint.tar.gz Signed-off-by: Adrian Reber <areber@redhat.com>
