ContainersOf() is better in almost every aspect, besides creating a session when the containers number is between 1024 and 2048 (prefetch script does limited unwrapping). Making List() private helps to ensure it is no longer used and can be safely removed in future. Signed-off-by: Evgenii Stratonikov <e.stratonikov@yadro.com>
