Connection migration to other server seemlessly.

[chikilov]

Is your feature request related to a problem? Please describe. I am using gnet framework with 30k clients. And use aws codedeploy (blue/green). When I deploy new version of source all connection close and reconnect to new server at once. It might be cause a kind of performance issue. So I try to use onShutdown event, Unfortunately, it fires after all connection closed.

Describe the solution you'd like Can you make a new event type just before start shut down?

Describe alternatives you've considered
