Allow changing of port forward rules on restore
Restored containers, until now, had the same port mappings as the
original started container. This commit adds the parameter '--publish'
to 'podman container restore' with the same semantic as during
create/run.
With this change it is possible to create a copy from a container with a
'--publish' rule and replace the original '--publish' setting with a new
one.
# podman run -p 2345:8080 container
# podman container checkpoint -l --export=dump.tar
# podman container restore -p 5432:8080 --import=dump.tar
The restored container will now listen on localhost:5432 instead of
localhost:2345 as the original created container.
