Returns a list of orderable cluster options. Before you create a         new cluster
            you can use this operation to find what options are         available, such as the
            EC2 Availability Zones (AZ) in the specific         AWS region that you can specify,
                    and the node types you can request. The node types differ by available   
                 storage, memory, CPU and price. With the cost involved you might want to    
                obtain a list of cluster options in the specific region and specify values   
                 when creating a cluster.         For more information about managing clusters,
