event bus registrations cleared when new zookeeper session is build

[lihui920913]

It is noticed that event bus address snapshot are only restored when session is reconnected. That means, when a session lost after retrying several times dual to its retry policy, then, next time the client connected successfully, a new session is build and all event bus registrations are lost. Am i assuming correctly ? if so, is that reasonable ?

I also encountered the same problem, maybe we can talk, I have an idea, but some problems encountered in implementation have not been resolved
