--
-- Adds one or more tags to an IAM role. The role can be a regular role or
-- a service-linked role. If a tag with the same key name already exists,
-- then that tag is overwritten with the new value.
--
-- A tag consists of a key name and an associated value. By assigning tags
-- to your resources, you can do the following:
--
-- -   __Administrative grouping and discovery__ - Attach tags to resources
--     to aid in organization and search. For example, you could search for
--     all resources with the key name /Project/ and the value
--     /MyImportantProject/. Or search for all resources with the key name
--     /Cost Center/ and the value /41200/.
--
-- -   __Access control__ - Include tags in IAM user-based and
--     resource-based policies. You can use tags to restrict access to only
--     an IAM role that has a specified tag attached. You can also restrict
--     access to only those resources that have a certain tag attached. For
--     examples of policies that show how to use tags to control access,
--     see
--     <https://docs.aws.amazon.com/IAM/latest/UserGuide/access_tags.html Control access using IAM tags>
--     in the /IAM User Guide/.
--
-- -   __Cost allocation__ - Use tags to help track which individuals and
--     teams are using which Amazon Web Services resources.
--
-- -   If any one of the tags is invalid or if you exceed the allowed
--     maximum number of tags, then the entire request fails and the
--     resource is not created. For more information about tagging, see
--     <https://docs.aws.amazon.com/IAM/latest/UserGuide/id_tags.html Tagging IAM resources>
--     in the /IAM User Guide/.
--
-- -   Amazon Web Services always interprets the tag @Value@ as a single
--     string. If you need to store an array, you can store comma-separated
--     values in the string. However, you must interpret the value in your
--     code.
--
-- For more information about tagging, see
-- <https://docs.aws.amazon.com/IAM/latest/UserGuide/id_tags.html Tagging IAM identities>
-- in the /IAM User Guide/.
