Update cluster documentation

Description

We should update the Cluster documentation, if possible before releasing 2.3.

I set up a Bro cluster for the first time yesterday - and when you look at the current state at the documentation it is not very useful...

...for example it contains things like (link to an example for the config) in the text. Furthermore it does not really mention how to actually configure Bro for a cluster, there is no mention of node.cfg, etc.
