     * 种子节点地址
     *      *     格式： ip:port
     *
     *     -- 生产环境的建议 --
     *     注意，在生产上建议一台物理机配置一个 broker （游戏网关）
     *     一个 broker 就是一个节点
     *     比如配置三台机器，端口可以使用同样的端口，假设三台机器的 ip 分别是:
     *     192.168.1.10:30056
     *     192.168.1.11:30056
     *     192.168.1.12:30056
     *
     *
     *     -- 注意这里如果没设置，构建器会给一个默认值用于测试 --
     *     这里配置写死是方便在一台机器上启动集群
     *     但是同一台机器启动多个 broker 来实现集群就要使用不同的端口，因为《端口被占用，不能相同》
     *     所以这里的配置是：
     *     127.0.0.1:30056
     *     127.0.0.1:30057
