  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, go to <a
