-- Pause an active App Runner service. App Runner reduces compute capacity
-- for the service to zero and loses state (for example, ephemeral storage
-- is removed).
--
-- This is an asynchronous operation. On a successful call, you can use the
-- returned @OperationId@ and the ListOperations call to track the
-- operation\'s progress.
