> Both sides on a DoPut should be able to half-close the stream, indicating
> they will no longer write. This allows a client to indicate that it is done
> writing data to the server, while still leaving the stream open so it can
> read metadata responses until the server finishes. Meanwhile, the server
> would see that the client has finished and be able to stop blocking on
> reading client messages.
