Doesn't work Ray client on k8s with Ingress

Ray Core Ray Client

Hi @Dmitri

I resolved this issue.

According to configuration of ingress, Ingress Controller remove the invalid header on gRPC protocol. So they remove the ‘client_id’ header in the request which is sent from Ray Client.
I found the solution to resolve this issue here.

I resolved by adding the following Ingress annotation.

metadata:
  annotations:
    nginx.ingress.kubernetes.io/server-snippet: |
      underscores_in_headers on;
      ignore_invalid_headers on;

I think it’d better to add the guide this issue on Ray Client guide.
I sent the PR adding the Ray Client guide. ([RayClient] Add the guide for k8s Ingress by 77loopin · Pull Request #17736 · ray-project/ray · GitHub)
