-- Lists all tags currently on a named resource.
--
-- A tag is a key-value pair where the key and value are case-sensitive.
-- You can use tags to categorize and track all your ElastiCache resources,
-- with the exception of global replication group. When you add or remove
-- tags on replication groups, those actions will be replicated to all
-- nodes in the replication group. For more information, see
-- <http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/IAM.ResourceLevelPermissions.html Resource-level permissions>.
--
-- If the cluster is not in the /available/ state, @ListTagsForResource@
-- returns an error.
