storage_options arg in to_zarr?

[raybellwaves]

Is there a storage_options arg in to_zarr similar to dask.array.to_zarr?

I know open_dataset can make use of backend_kwargs=dict(storage_options=storage_options).

It seems that this still works by having to create your own mapping store (fs.get_mapper) as a separate step. Adding storage_options, as with the read side, would be very reasonable.
