         * zookeeper缺省支持下面几种scheme:
         *
         * 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)
