-- 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.
