Now in com.alibaba.nacos.client.naming.core.EventDispatcher.Notifier.run, when get serviceChange from server, it will notify com.alibaba.nacos.client.naming.core.EventDispatcher.Notifier.run, find listener by serviceKey, and execute the callback.
But the callback is sync to execute, if some long time operation in the callback, it will blocking other service's notify.
Shall we add some info in docs to hint user, this callback is sync, if do long time operation, it will influence other listener or service to notify. let user execute it by thread they defined by themselves.
Or execute callback in thread pool which realized by framework.
