Releases a cluster.


After a cluster is released, the pay-as-you-go nodes and the subscription nodes that have expired are automatically released. The subscription nodes that have not expired are retained. If you need to release the subscription nodes that have not expired, change their billing method to pay-as-you-go. Before you release a cluster, make sure that you will no longer use the cluster.
