Title: Cluster 2.0 – step 5 : Make setupMaster to public API

This make the `setupMaster` public API.

**It allow:**
* workers to not relay `stderr` and `stdout` data
* Custom child `args`
* To have workers and master in separate files.

When the cluster is initialized a `setup` event is emitted and the `cluster.settings` is set. This allow module (cluster plugins) to know the cluster settings there was used.

@mscdex @visionmedia @ry please review

_This is about the merging in the `cluster 2.0` ( see #2038 ) pull request_
