-- The /ListTagsForResource/ action lists all cost allocation tags
-- currently on the named resource. A /cost allocation tag/ is a key-value
-- pair where the key is case-sensitive and the value is optional. Cost
-- allocation tags can be used to categorize and track your AWS costs.
--
-- You can have a maximum of 10 cost allocation tags on an ElastiCache
-- resource. For more information, see
-- <http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/BestPractices.html Using Cost Allocation Tags in Amazon ElastiCache>.
