container_run_and_commit and container_run_and_extract don't support the intermediate format because they were moved from https://github.com/GoogleContainerTools/base-images-docker.

Issue Number: 1384

What is the new behavior?

Support incremental loading in the two rules so that they can depend on container_image rules' layer outputs instead of having to depend on the image tarball.

Sorry to ask this of you @uhthomas but given the effort put into #1439 that didn't pan out I'm hesitant to spend more time on this, can you take this over?

@lamcw looks like the CLA check is failing because you're the author of the commit, can you submit one via https://cla.developers.google.com?

[uhthomas]

I understand @uri-canva, no worries. I can't guarantee I'll get round to it though I appreciate you making the effort to update this PR with your latest changes.
