-- The /ResetCacheParameterGroup/ action modifies the parameters of a cache
-- parameter group to the engine or system default value. You can reset
-- specific parameters by submitting a list of parameter names. To reset
-- the entire cache parameter group, specify the /ResetAllParameters/ and
-- /CacheParameterGroupName/ parameters.
