[Docs] Add example for multiple machine pools

[smoothzz]

Issue: #1186

This adds example for adding multiple machine pools, in the docs it says that it is a list, but after a few tests i realized that this is the right way. So would be good to have example in the official docs.

Thanks @smoothzz - this helped me!

In your example you create 1 master with all three roles and 2 worker with only worker role. Maybe it would make sense to change this to 3 master where the masters do not have the worker role and 4 workers that just have the worker role?
(Would make the cluster fault tolerant and the example more aligned with real world deployments)

@Martin-Weiss yeah definitely.

@smoothzz Can you run a gofmt -w on your updated files? And/or rebase with the latest master? I think CI is failing because your branch is outdated over a year
