dapr.aio.clients subscribe_configuration implemented synchronously

[zgxkbtl]

I ran into an issue with aio. When I use aio.clients to call subscribe_configuration, _read_subscribe_config is still implemented synchronously, so stub.SubscribeConfigurationAlpha1(req) returns an _AioCall object that isn’t iterable.
