Why are these changes needed?

In #1835, we don't store logger into context for RayJob controller. #1894 calls ctrl.LoggerFrom, which retrieves a default logger containing metadata information about the controller and K8s resources. This PR stores the logger into context to keep the consistent logging format. In the future, we may need to add controller/CR metadata to the logger for better structured logging.
