'disconnect' event is not emitted on cluster.worker

[Olegas]

Demo app here: https://gist.github.com/Olegas/c2e5550911cbe8b96dae

Steps to reproduce:

1. Start app, wait 10 sec
2. App is terminated and log show the following lines

Master started
Worker started
Worker listening
Disconnecting worker
Cluster: worker is disconnected

Expected result:
Line Worker disconnected (from https://gist.github.com/Olegas/c2e5550911cbe8b96dae#file-demo-js-L26) is present in log as stated in docs: https://iojs.org/api/cluster.html#cluster_event_disconnect_1

If I change line 25 to cluster.worker.process.on('disconnect', ... it works fine.

Can we just add worker.emit('disconnect'); just above this line: https://github.com/iojs/io.js/blob/v1.x/lib/cluster.js#L510

@Olegas that sounds correct to me. Currently, there is no parallel for this in the cluster child process worker. Do you want to open a PR, or should I?

[Olegas]

I'll do
