// Connects a Kubernetes cluster to the Amazon EKS control plane. Any Kubernetes
// cluster can be connected to the Amazon EKS control plane to view current
// information about the cluster and its nodes. Cluster connection requires two
// steps. First, send a RegisterClusterRequest to add it to the Amazon EKS control
// plane. Second, a Manifest (https://amazon-eks.s3.us-west-2.amazonaws.com/eks-connector/manifests/eks-connector/latest/eks-connector.yaml)
// containing the activationID and activationCode must be applied to the
// Kubernetes cluster through it's native provider to provide visibility. After the
// Manifest is updated and applied, then the connected cluster is visible to the
// Amazon EKS control plane. If the Manifest is not applied within three days, then
// the connected cluster will no longer be visible and must be deregistered. See
// DeregisterCluster .
