Better documentation for local deploy

Hi,

I'm opening this issue because documentation about local instance is not complete imo, I was able to run a local instance with:

`python butler.py run_server`

And then a bot instance using:

`python butler.py run_bot --name my-bot /path/to/my-bot`

And finally I tried with heartbleed example and it works like by documentation.
Pretty easy till this point, anyway is not specified how to scale this "local" clusterfuzz instance for example I have multiple computer it's possible to run multiple bots connected to the main clusterfuzz instance? There is a way to start clusterfuzz and bots with systemd (as a service), a bot can run mutiple tasks? Can I specify which bot should run a specific task? There's a configuration file where I can set all those things? It's possible to access clusterfuzz from another PC in the same lan without port-forwarding / vnc or similar? I can't find an answer to those kind of question inside the documentation, can someone point me on the right way?

Thanks much
