Jarek Kowalski 6cb9b8fa4f repo: refactored public API (#318)
* This is 99% mechanical:

Extracted repo.Repository interface that only exposes high-level object and manifest management methods, but not blob nor content management.

Renamed old *repo.Repository to *repo.DirectRepository

Reviewed codebase to only depend on repo.Repository as much as possible, but added way for low-level CLI commands to use DirectRepository.

* PR fixes
