-- Gets all labels or a specific label if name is provided. This is a
-- paginated API. If you provide a null @maxResults@, this action retrieves
-- a maximum of 50 records per page. If you provide a @maxResults@, the
-- value must be between 10 and 50. To get the next page results, provide
-- the pagination token from the @GetGetLabelsResponse@ as part of your
-- request. A null pagination token fetches the records from the beginning.
