Answer 1

Autoscaling is set on instance groups, not on clusters.

If you want to see all the instance groups' autoscaling policies, you will first need to get the list of all clusters and then get the instance groups of each cluster.

Notice that in the response to get_instance_groups, you get the AutoScalingPolicy value.
