UpdateStack support for AWS::AutoScaling::AutoScalingGroup

Registered by Steven Hardy

Implement UpdateStack support for AutoScalingGroup - currently any attempt to update results in replacement, so we should align better with the AWS UpdateStack behavior for this resource. At a minimum it should be possible to update the properties which affect the scaling (MinSize, MaxSize, Cooldown) without replacing the group (and thus all the instances)
