We require middlewares by `require_dependency`.

This is not exactly correct. I found a nice explanation about this https://ieftimov.com/post/writing-rails-middleware/

So we should put the middlewares in lib/middleware/foreman instead of lib/foreman/middleware and use Foreman::NameOfMiddleware and use

config.middleware.use "Foreman::NameOfMiddleware"
That way Rails will do it's magic and require the middlewares for us no need to do this explicitly.

We should just use regular require and be done with it, as a conclusion of the https://github.com/rails/rails/issues/25525 suggests.
