Enable client server in 1.2.0 in Kubernetes

In 1.2.0. Seems user has to explicitly enable client server to use ray.util.connect ? How to start python -m ray.util.client.server in ray/example_cluster.yaml at ray-1.2.0 · ray-project/ray · GitHub?

I tried to change this line ray/example_cluster.yaml at b87fc1be5505c577f01807fd342e0cdb2e129081 · ray-project/ray · GitHub to ulimit -n 65536; python -m ray.util.client.server but seems blocks operator to work normally

cc @ijrsvt Can you address his question?

Can you run python -m ray.util.client.server &? The ray client server command is blocking, so the operator never finishes starting ray.
