In #265, we're adding a doc parameter to the grpc_data_property wrappers, to set the docstring on the properties. However, to avoid duplication of the docstring itself it's only set on read-only properties (where the same information doesn't need to be specified in the Parameters section of the __init__ docstring.
We should find a way to de-duplicate this information while still documenting it both on the property itself, and in the Parameters. Probably, the Parameters section can be auto-generated from the property docstrings.
