/**
 * Cloud Storage uses access control lists (ACLs) to manage object and
 * bucket access. ACLs are the mechanism you use to share objects with other
 * users and allow other users to access your buckets and objects.
 *
 * An ACL consists of one or more entries, where each entry grants permissions
 * to an entity. Permissions define the actions that can be performed against
 * an object or bucket (for example, `READ` or `WRITE`); the entity defines
 * who the permission applies to (for example, a specific user or group of
 * users).
 *
 * The `acl` object on a Bucket instance provides methods to get you a list of
 * the ACLs defined on your bucket, as well as set, update, and delete them.
 *
 * Buckets also have
 * {@link https://cloud.google.com/storage/docs/access-control/lists#default| default ACLs}
 * for all created files. Default ACLs specify permissions that all new
 * objects added to the bucket will inherit by default. You can add, delete,
 * get, and update entities and permissions for these as well with
 * {@link Bucket#acl.default}.
 *
 * See {@link http://goo.gl/6qBBPO| About Access Control Lists}
 * See {@link https://cloud.google.com/storage/docs/access-control/lists#default| Default ACLs}

 * {@link https://cloud.google.com/storage/docs/access-control/lists#default| default ACLs}
 * for all created files. You can add, delete, get, and update entities and
 * permissions for these as well. The method signatures and examples are all
 * the same, after only prefixing the method call with `default`.
 *
 * @example
 * ```
 * const {Storage} = require('@google-cloud/storage');
 * const storage = new Storage();
 *
 * //-
 * // Make a bucket's contents publicly readable.
 * //-
 * const myBucket = storage.bucket('my-bucket');
 *
 * const options = {
 *   entity: 'allUsers',
 *   role: storage.acl.READER_ROLE
 * };
 *
 * myBucket.acl.add(options, function(err, aclObject) {});
 *
 * //-
 * // If the callback is omitted, we'll return a Promise.
 * //-
 * myBucket.acl.add(options).then(function(data) {
 *   const aclObject = data[0];
 *   const apiResponse = data[1];
