mark ContainerImage.names as optional

Browse Source 
kubelet is the only writer of v1.Node .status.images[].names. When an
image has neither RepoDigests nor RepoTags, the value gets stored in
etcd as null. Marking the field as optional can help JSON API clients
to avoid hitting serialization error when the returned status contains
null .status.images[].names.
