         MQ管理接口配置
         不同MQ节点所配置的MQ集群不能重复。
         MQ跟着协议走，所以mq的属性值需要被赋值在rest节点上, 由于SncpServlet是自动生成的，故SNCP协议下，mq属性值被赋值在service/services节点上
-        name:   服务的名称，用于监控识别，多个mq节点时只能有一个name为空的节点，mq.name不能重复,命名规则: 字母、数字、下划线
-        type： 实现类名，必须是org.redkale.mq.MessageAgent的子类
-        coder: MessageRecord的解析器类，必须是org.redkale.mq.MessageCoder<MessageRecord>的实现类, 
-               可对数据包进行加密解密，默认值：org.redkale.mq.MessageRecordCoder
