How tough would it be to dump the full image digest as part of this? That way we could debug later.

Only one of these should be a daemon.Image, right? The other is remote?

@dlorenc the kaniko image is pulled right before this executes (maybe that should be made more clear somehow?)

Latest kokoro failure is a test timeout, very odd 🤔 |
In GoogleContainerTools#251 we are investigating test flakes due to layer offsets not matching, this change will give us a bit more context so we can be sure which image has which number of layers, and it will also include the digest of the image, since kaniko always pushes images to a remote repo, so if the test fails we can pull the digest and see what is up. Also updated reproducible Dockerfile to be built with reproducible flag, which I think was the original intent (without this change, there is no difference between how `kaniko-dockerfile_test_copy_reproducible` and `kaniko-dockerfile_test_copy` are built.
