/**
 * Creates a query to retrieve a list of labels.
 *
 * The `queryLabels()` method builds a query to retrieve a list of labels and returns a `LabelsQueryBuilder` object.
 *
 * The returned object contains the query definition, which is used to call the query using the `find()` method.
 *
 * You can refine the query by chaining `LabelsQueryBuilder` methods onto the query. `LabelsQueryBuilder` methods enable you to filter, sort, and control the response that `queryLabels()` returns.
 *
 * `queryLabels()` is called with the following `LabelsQueryBuilder` defaults, which you can override:
 * - `skip(0)`
 * - `limit(50)`
 * - `descending('_createdDate')`
 *
 * The following `LabelsQueryBuilder` methods are supported for `queryLabels()`. For a full description of the `Labels` object, see the object returned for the `items` field in `LabelsQueryResult`.
