config: simplify structureconfig-code-format

* Replace `require_relative` with `require`
  The project tries to use the `require` form everywhere where possible, which
  is the common form
* `require` from `pry.rb`
  Spreaded `require` statements where we require internal classes is confusing
* Fixed namespace definition for Config classes
  https://github.com/rubocop-hq/ruby-style-guide#namespace-definition recommends
  to use explicit nesting
