Schema api not supporting pubsub emulator

[bealsao]

The schema_service/client.py did not receive the fixes in this change: 297

So you receive the same errors as described in the issue: 290

I have created a fork where I added the code and verified this is all that needs to change for this to work with the pubsub emulator:

            emulator_host = os.environ.get("PUBSUB_EMULATOR_HOST")
            if emulator_host:
                if issubclass(Transport, type(self)._transport_registry["grpc"]):
                    channel = grpc.insecure_channel(target=emulator_host)
                else:
                    channel = grpc.aio.insecure_channel(target=emulator_host)
                Transport = functools.partial(Transport, channel=channel)

The fix is extremely simple as the work has already been done :)
