Why are these changes needed?

Adds "NumOfHosts" as an int32 field in RayCluster CR's WorkerGroupSpec section. NumOfHosts will be used to denote WorkerGroup replicas consisting of multiple hosts (for example, TPU hosts in a multi-host pod).

  1. Should we add omitempty to make this field optional?
  2. Perhaps we could use int32 instead to avoid some nil checks.
