--
-- Assigns one or more tags (key-value pairs) to the specified CloudWatch
-- resource. Currently, the only CloudWatch resources that can be tagged
-- are alarms and Contributor Insights rules.
--
-- Tags can help you organize and categorize your resources. You can also
-- use them to scope user permissions by granting a user permission to
-- access or change only resources with certain tag values.
--
-- Tags don\'t have any semantic meaning to Amazon Web Services and are
-- interpreted strictly as strings of characters.
--
-- You can use the @TagResource@ action with an alarm that already has
-- tags. If you specify a new tag key for the alarm, this tag is appended
-- to the list of tags associated with the alarm. If you specify a tag key
-- that is already associated with the alarm, the new tag value that you
-- specify replaces the previous value for that tag.
--
-- You can associate as many as 50 tags with a CloudWatch resource.
