Parallelize operations with docker registry
- parallel read/delete stages from stages-storage operations;
- parallel read/delete images info from images-repo operations;
- image metadata cache;
- add --parallel and --parallel-tasks-limit options for cleanup (by default, parallelization is enabled and tasks limit is 5).
Other fixes
- Do not lock cleanup process by images-repo.
- Push image with retries when specific errors occur.
