-- Returns the current @LifecycleConfiguration@ object for the specified
-- Amazon EFS file system. EFS lifecycle management uses the
-- @LifecycleConfiguration@ object to identify which files to move to the
-- EFS Infrequent Access (IA) storage class. For a file system without a
-- @LifecycleConfiguration@ object, the call returns an empty array in the
-- response.
--
-- When EFS Intelligent-Tiering is enabled,
-- @TransitionToPrimaryStorageClass@ has a value of @AFTER_1_ACCESS@.
--
-- This operation requires permissions for the
-- @elasticfilesystem:DescribeLifecycleConfiguration@ operation.
