-- Shows usage limits on a cluster. Results are filtered based on the
-- combination of input usage limit identifier, cluster identifier, and
-- feature type parameters:
--
-- -   If usage limit identifier, cluster identifier, and feature type are
--     not provided, then all usage limit objects for the current account
--     in the current region are returned.
--
-- -   If usage limit identifier is provided, then the corresponding usage
--     limit object is returned.
--
-- -   If cluster identifier is provided, then all usage limit objects for
--     the specified cluster are returned.
--
-- -   If cluster identifier and feature type are provided, then all usage
--     limit objects for the combination of cluster and feature are
--     returned.
--
-- This operation returns paginated results.
