    Interface used by ``save_state_dict`` to write to storage.

    One StorageWriter instance acts as both the coordinator and the follower

    is told its role.

    A subclass should expect the following sequence of calls.

        A checkpoint_id may be present if users set the checkpoint_id for
        this checkpoint write. The meaning of the checkpiont_id is
        storage-dependent. It can be a path to a folder/file or a key for
        a key-value storage.

                The ID of this checkpoint instance. The meaning of the checkpoint_id

        Write all items from ``plan`` using ``planner`` to resolve the data.

        A subclass should call ``SavePlanner::resolve_data`` on each item
        from the plan to get access to the underlying object to write.

        Subclasses should lazily call `resolve_data` as it can allocate memory.
        In case of tensors, make following assumptions:

        - They might be on any device, including not matching the one on ``WriteItem::tensor_data``
        - They might be views or not contiguous. Only the projection needs to be saved.

        Args:
            plan (SavePlan): The save plan to execute.
            planner (SavePlanner): Planner object to be used to resolve items to data.

        The actual format/schema used for serializing `metadata` is an
