Ability to define the AutoScalingGroup GlobalTimeout

For login/compute nodes that takes longer than 10 minutes to complete, the instance is killed after initialization due to heartbeat-timeout for the aws autoscaling group lifecycle hooks.

We operate a cluster with SELinux enabled, so relabeling takes a very long time(on our efs and lustre), and would have to manually update the ec2 autoscaling group with a higher timeout so that our nodes stay alive after being spun up.
