-- Gets a metrics configuration (specified by the metrics configuration ID)
-- from the bucket. Note that this doesn\'t include the daily storage
-- metrics.

-- To use this operation, you must have permissions to perform the
-- @s3:GetMetricsConfiguration@ action. The bucket owner has this
-- permission by default. The bucket owner can grant this permission to
-- others. For more information about permissions, see
