Supported operations

OpenSearch并不是支持所有原生的API，例如/_ilm/或/_cluster/settings的某些接口，会报：

{"Message":"Your request: '/_cluster/settings' payload is not allowed."} 401 Unauthorized

参考： https://docs.aws.amazon.com/opensearch-service/latest/developerguide/supported-operations.html#version_7_10

里面会有支持的API列表：
