Overview

Note:

If you want to do some configurations after all of this is done, please add to karafka/config a proper file (needs to inherit from Karafka::Setup::Configurators::Base and implement setup method) after that everything will happen automatically

Note:

This config object allows to create a 1 level nesting (nodes) only. This should be enough and will still keep the code simple
