AWS VPC CNI Version 1.5.0 Now Default for Amazon EKS Clusters

Version 1.5 of the AW VPC CNI plugin improves the behavior of the WARM_IP_TARGET parameter so that any IPs not assigned to pods will be returned back to the subnet. This lowers overall IP address utilization across the cluster. Additionally, a number of bug fixes improve the overall reliability and performance of the CNI for Amazon EKS clusters.
