To ensure kubelet doesn't attempt network teardown on HostNetwork containers that no longer exist but are still checkpointed, make sure we preserve the HostNetwork property in checkpoints. If the checkpoint indicates the container was a HostNetwork one, don't tear down the network since that would fail anyway.
