    This is an interface which allows user to create more advanced
    sharding strategies that are not easily be composed by the
    `ShardingSpec`.

    :class:`torch.distributed._shard.sharding_plan.ShardingPlan` could
    take an object of the `Sharder` and call `shard` to shard the module,
    then replace the original module with sharded module returned.

        Shard a module base on the implementation of this method, and
        return the sharded version of the module.

        Args:
            module (:class:`torch.nn.Module`):
                The module to apply sharding to.
        Returns:
            A :class:`torch.nn.Module` object that represents a module
            that's already been sharded.
