Review comment:
To avoid behavior change, it would be better to keep it `false` but
keeping container images in the local repository is side effect and done
implicitly before this change. So I thought it is better do keep the images
only if users can explicitly set the property to `false`.
Any thoughts? @dongjoon-hyun @HyukjinKwon
