title: How can I set the MAX capacity of an autoscaling group with boto3?
body: <p>Lets say I have a cluster with 3 instances, and when it was created I wanted 3 instances. I can use a scaling policy to manipulate it between 0-3 but obviously it hits the limit of the MAX capacity.</p>
  
  <p>I can update this on the front end but don't see an API call for it. </p>
  
  <p>How do I set the max capacity of an autoscaling group?</p>
  
  <p>Ideally there is a way to do this without creating a new one then deleting the old one. If that is the only way, do I need to make the cluster "aware" of the new scaling group?</p>
