// 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.
