-- Returns a description of the settings for the specified configuration
-- set, that is, either a configuration template or the configuration set
-- associated with a running environment.
--
-- When describing the settings for the configuration set associated with a
-- running environment, it is possible to receive two sets of setting
-- descriptions. One is the deployed configuration set, and the other is a
-- draft configuration of an environment that is either in the process of
-- deployment or that failed to deploy.
