• I had searched in the issues and found no similar feature requirement.

Description

Currently we have a global flag to disable zero downtime upgrades for ALL RayService resources. It would be great to have a flag in the CRD to disable zero-downtime upgrade for a specific RayService resource.

Use case

We're managing multiple RayService resources, and want to disable zero-downtime upgrade in one of the resources.

I would be in favor of a new field in RayService to toggle the upgrade policy. We can default it to zero-downtime upgrade for compatibility. What do you think @kevin85421

There are some other proposals floating around for supporting N RayCluster per RayService as well, it might be good to revisit this as part of those proposals.

I would also be in favor of having N RayCluster per RayService!
