         * world: 默认方式,相当于全世界都能访问; 它下面只有一个id, 叫anyone, world:anyone代表任何人,zookeeper中对所有人有权限的结点就是属于world:anyone的
         * auth: 代表已经认证通过的用户(cli中可以通过addauth digest user:pwd 来添加当前上下文中的授权用户); 它不需要id, 只要是通过authentication的user都有权限(zookeeper支持通过kerberos来进行authencation, 也支持username/password形式的authentication)
         * digest: 即用户名:密码这种方式认证,这也是业务系统中最常用的;它对应的id为username:BASE64(SHA1(password)),它需要先通过username:password形式的authentication
         * ip: 使用Ip地址认证;它对应的id为客户机的IP地址,设置的时候可以设置一个ip段,比如ip:192.168.1.0/16, 表示匹配前16个bit的IP段
         * super: 在这种scheme情况下,对应的id拥有超级权限,可以做任何事情(cdrwa)
