rename pod when we have a name collision with a container

when podman generate kube runs, it names the pod based on the first
container it finds. the resulting yaml file is perfectly acceptable
in a kubernetes environment.  But when replaying the YAML file
with podman, we cannot have a container and pod with the same name.
therefore, we rename the pod if find a collision to name_pod.
