cleanup-security-group misses elb security groups

[dpedu]

Describe the bug
I ran this tool and it deleted the cluster's security group but not groups created for load balancers.

To Reproduce

• Create an eks service with load balancer
• Delete the service (LB automatically removed, leaves orphan security groups in certain situations)
• Call kubergrunt.

resource "aws_eks_cluster" "eks" {
   ...
  provisioner "local-exec" {
    when    = destroy
    command = "kubergrunt eks cleanup-security-group --eks-cluster-arn ${self.arn} --security-group-id ${self.vpc_config.0.cluster_security_group_id} --vpc-id ${self.vpc_config.0.vpc_id}"
  }
}

Expected behavior
Kubergrunt deletes the orphaned load balancer security groups.

Nice to have

Additional context
The orphaned security groups have a tag like: kubernetes.io/cluster/<clustername>=owned. See kubernetes/kubernetes#109698 for the conditions under which these orphaned groups are created and not deleted.
