// Assigns one or more tags (key-value pairs) to the specified CloudWatch Logs
// resource. Currently, the only CloudWatch Logs resources that can be tagged are
// log groups and destinations.
//
// 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 a resource 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 Logs resource.
