Use layers digest for CacheID in FROM step #307

Using layers digest for calculating cacheID allows to use cache between different image tags. This can be very useful if there's a lot of similar images with different tags, for example, in a CI/CD pipeline where each feature branch produces different image tag.

I think the best approach should be using SHA256 hash of manifest content.
