[aws-eks] There is already a Construct with name 'chart-spot-interrupt-handler' in Cluster [EKSCluster]

[chrisdrobison]

Adding two autoscaling groups that are both spot will result in an error:

There is already a Construct with name 'chart-spot-interrupt-handler' in Cluster [EKSCluster]

The reason I would do this is if I need to create a worker node group with a taint set for special work loads.

Reproduction Steps

const eksCluster = new eks.Cluster(this, "EKSCluster", {
            vpc: vpc,
            vpcSubnets: [
                { subnetType: ec2.SubnetType.PRIVATE }
            ],
            version: "1.15",
            defaultCapacity: 0
        });

        const autoScalingGroup = new autoscaling.AutoScalingGroup(this, "Worker-Group", {
            vpc: vpc,
            instanceType: new ec2.InstanceType("t3a.xlarge"),
            machineImage: ec2.MachineImage.lookup({ name: "custom-image-name" }),
            minCapacity: 1,
            maxCapacity: 10,
            updateType: autoscaling.UpdateType.ROLLING_UPDATE,
            spotPrice: '0.10'
        });
        eksCluster.addAutoScalingGroup(autoScalingGroup, {});

        const autoScalingGroup2 = new autoscaling.AutoScalingGroup(this, "Worker-Group-2", {
            vpc: vpc,
            instanceType: new ec2.InstanceType("t3a.xlarge"),
            machineImage: ec2.MachineImage.lookup({ name: "custom-image-name" }),
            minCapacity: 1,
            maxCapacity: 10,
            updateType: autoscaling.UpdateType.ROLLING_UPDATE,
            spotPrice: '0.10'
        });
        eksCluster.addAutoScalingGroup(autoScalingGroup2, {});
