Provides the status of all clusters visible to this AWS account. Allows you to filter
            the list of clusters based on certain criteria; for example, filtering by cluster
            creation date and time or by status.         This call returns a maximum of 50 clusters
            per call, but returns a marker to track the paging of the cluster list across multiple
            ListClusters calls.
