[Feature Request] Support in place callbacks

[aka-momo]

Elevator pitch, describe and sell us your feature request

As a developer,
I want be able to attach callbacks on the organizer's level
so that I be able to re-use interactors in different contexts

Is your feature request related to a problem

I'm always frustrated when I need to use a specific interactor in different contexts.

Sometimes a specific interactor is built to expect a specific input for example user_id while the current context has user object instead, I need to be able to set the user id before the execution of this interactor.

class TestOrganizer < ActiveInteractor::Organizer::Base
  organize do
    add :update_username
    add :find_user_token_by_user_id, before: -> { context.user_id = context.user.id }
    add :baz_interactor
  end
end

Have you considered any alternatives

From the example mentioned above, I can create another command called find_user_token_by_user to expect a user object instead of user_id but it causes unnecessary logic duplication.

Additional Comments

Another use case if to be able to fail context after an execution of a specific interactor only in this context.

class TestOrganizer < ActiveInteractor::Organizer::Base
  organize do
    add :foo_interactor
    add :bar_interactor, after: -> { context.fail! if context.something == false }
    add :baz_interactor
  end
end
