-- Retrieve a list of the tags (keys and values) that are associated with a
-- specified application. A /tag/ is a label that you optionally define and
-- associate with an application. Each tag consists of a required /tag key/
-- and an optional associated /tag value/. A tag key is a general label
-- that acts as a category for more specific tag values. A tag value acts
-- as a descriptor within a tag key.
