ReferencedImageConfigEdgeKind defines an edge from an ImageStreamNode or an ImageNode to an ImageComponentNode.

ReferencedImageEdgeKind defines a "strong" edge where the tail is an ImageNode, with strong indicating that the ImageNode tail is not a candidate for pruning.

ReferencedImageLayerEdgeKind defines an edge from an ImageStreamNode or an ImageNode to an ImageComponentNode.

ReferencedImageManifestEdgeKind defines an edge from an ImageStreamNode or an ImageNode to an ImageComponentNode.

WeakReferencedImageEdgeKind defines a "weak" edge where the tail is an ImageNode, with weak indicating that this particular edge does not keep an ImageNode from being a candidate for pruning.
