 If `enableSQSTerminationDraining` is true Node Termination Handler will operate in Queue Processor mode. In addition to the events mentioned above, Queue Processor mode allows Node Termination Handler to take care of ASG Scale-In, AZ-Rebalance, Unhealthy Instances, EC2 Instance Termination via the API or Console, and more. kOps will provision the necessary infrastructure: an SQS queue, EventBridge rules, and ASG Lifecycle hooks. `managedASGTag` can be configured with Queue Processor mode to distinguish resource ownership between multiple clusters.
 
 The kOps CLI requires additional IAM permissions to manage the requisite EventBridge rules and SQS queue:
