redis 配置

1、我在使用的时候，重新配置了Hyperf\SocketIOServer\Room\AdapterInterface::class的对应关系，并在构造函数中修改了redis的配置信息，将dbIndex从0改动到了3.启动后数据仍然保存在db0中，如果通过watcher监听器重启，数据会同时储存在db0和db3中。
2、引入的tarit类Emitter在Hyperf\SocketIOServer\BaseNamespace中，虽然书写的时候避免方法名称冲突，可以避免问题。但是如果使用调度器模式，是不是会更方便。

Start by reproducing the Redis dbIndex behavior after rebinding Hyperf\SocketIOServer\Room\AdapterInterface::class and after a watcher restart. Inspect the constructor configuration and Hyperf\SocketIOServer\BaseNamespace, including its Emitter usage and dispatcher-mode question. Done means the intended database is used consistently and the Emitter design question has a documented decision.
