[kolla-ansible][Antelope][Heat] Auto Scaling Group - Cancel Update

Hello,

We are working on a workflow to cancel in progress rolling updates for the resource

OS::Heat::AutoScalingGroup

When we run the command `openstack stack cancel <stack-id> it cancels the Heat stack update, but the Auto-Scaling group finishes updating all VMs in the group. We need a way to either rollback or completely cancel the Auto Scaling Group update and not replace any additional VMs. Any help would be appreciated.
