`cml runner` seems to ignore `--idle-timeout` on AWS

[iirekm]

My script: cml runner launch \ --repo=... \ --labels=cml-cloud --single --idle-timeout=120s \ --cloud=aws --cloud-region=us-east-1 --cloud-type=c6a.8xlarge

It seems to ignore --idle-timeout on AWS, while it worked well on GCP. The result is that my instances keep running forever and eating money.
