There are two ways to start an autoscaling cluster: manually by running
`ray start --head --autoscaling-config=/path/to/config.yaml` on a
instance that has permission to launch other instances, or you can also use
`ray up /path/to/config.yaml` from your laptop, which will
`ray create_or_update /path/to/config.yaml` from your laptop, which will
configure the right AWS/Cloud roles automatically.
StandardAutoscaler's `update` method is periodically called by `monitor.py`
