DEV: Allow CheckpointManagers to optimize for shared backends....

DEV: Allow CheckpointManagers to optimize for shared backends. On `create_checkpoint` and `restore_checkpoint`, pass a path and a `ContentsManager` to `CheckpointManager` instead of an already-loaded model. The `CheckpointManager` base class provides a correct implementation of these methods that's generic across any ContentsManager, but subclasses are free to specialize when the storage backend of `ContentsManager` is shared.
