`linuxkitprojects/kubernetes` → `linuxkitprojects/kubelet` `linuxkitprojects/kubernetes-image-cache-*` → `linuxkitprojects/kubernetes-docker-image-cache-*` `kubernetes` subdirectory is also renamed to `kubelet`. `image-cache` subdirectory is not renamed since we may want to build other sorts of image cache at some point.
