// TagResourceRequest returns a request value for making API operation for
// Amazon CloudWatch.
//
// 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 AWS 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.
