-- 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>.
