Review comment:
We really need len(self._environments) * num_workers, right?
Also, should we throw an error if this was previously initialized with too

> Because max_workers of grpc servers are hardcoded to 10, it only supports up
> to 10 workers, and if we pass more direct_num_workers greater than 10,
> pipeline hangs, because not all workers get connected to the runner.
