// Updates an Amazon EKS cluster to the specified Kubernetes version. Your cluster
// continues to function during the update. The response output includes an update
// ID that you can use to track the status of your cluster update with the
// DescribeUpdate API operation. Cluster updates are asynchronous, and they should
// finish within a few minutes. During an update, the cluster status moves to
// UPDATING (this status transition is eventually consistent). When the update is
// complete (either Failed or Successful ), the cluster status moves to Active . If
// your cluster has managed node groups attached to it, all of your node groups’
// Kubernetes versions must match the cluster’s Kubernetes version in order to
// update the cluster to a new Kubernetes version.
