Title: Add IPC channel disconnect method and process isolate method.  

This allow the following issues to be fixed:

* issue #2344
* issue #1740
* issue #2292
* issue #1363
* issue #2088

**disconnect:**
This allow one to disconnect the IPC between parent and child, allowing the child to die gracefull.

**isolate:**
This allow the parent to die gracefull independent of its child. This makes it easy to pull a process in the background should you wich so.

I have a felling that the `process._channel.close()` is async but do not have a callback, could you confirm or disconfirm this.

_This also solves some future issues related to `cluster 2.0` (see #2038)_
