To summarize, we'd like Docker, during a push of blob, to:
1. It could try to mount from each remembered association before falling back to full blob upload.
2. Verify if the blob really doesn't exist in the source repository before forgetting its association.
3. Stat() the target repository even if there's no remembered association between blob and the destination repository.
