[UX/Jobs] No spinner after jobs launch, which feels like a hang

[Michaelvll]

When launching a managed job where the controller is on k8s, there is no spinner showing up after the job is submitted, which feels like the system is hanging. However, sky jobs logs --controller does show that the job cluster is being launched.

Task from YAML spec: test.yaml
Managed job 'test-mount-bucket' will be launched on (estimated):
