 Async Query Result API
 ======================================
 If security plugin is enabled, this API can only be invoked by users with permission ``cluster:admin/opensearch/ql/async_query/result``.
 Async Query Creation and Result Query permissions are orthogonal, so any user with result api permissions and queryId can query the corresponding query results irrespective of the user who created the async query.
