Include infra container information in `pod inspect`
We had a field for this in the inspect data, but it was never being populated. Because of this, `podman pod inspect` stopped showing port bindings (and other infra container settings). Add code to populate the infra container inspect data, and add a test to ensure we don't regress again. Signed-off-by: Matthew Heon <mheon@redhat.com>
