lots of errors with "v2.4-rails" example

[ksimmi]

Hello,

I cloned this repo and tried to run "v2.4-rails" example and I got an error
uninitialized constant KarafkaApp::VisitsConsumer (NameError)

I fixed it by adding to karafka.rb

require_relative 'app/consumers/application_consumer'
require_relative 'app/consumers/visits_consumer'

After that I got a new error

undefined method `enable!' for Karafka::Web:Module (NoMethodError)

I fixed it by adding to karafka.rb

require 'karafka/web'

After that the example app was started.
