Add hoc sequences in create_list

Fixes #1647

Allow creation of sequence attributes in create_list

This PR is more of a proof of concept, if I get the green light I can add documentation and more tests if needed.

It is working and all tests pass, however I am not confident about the code structure..in this approach FactoryBot.build_sequence is just a syntactical sugar for a Proc, however it will work fine if we pass a Proc too. Is it better to have a dedicated class for this instead?

That was fast!

Is it better to have a dedicated class for this instead?

There's a backward compatibility issue to figure out. Imagine this:

class UserWithCallback
  def initialize(name, dob, on_save)
    @name = name
    @dob = dob
    @on_save = on_save
  end

  def save
    user = User.create!(name: @name, dob: @dob)
    @on_save.call(user)
  end
end

FactoryBot.define do
  factory :user_with_callback do
    name { "Zero Cool" }
    dob { "1988-08-10" }
    on_save do
      proc { |user| Logger.info("created user #{user}") }
    end
  end
end

This is, currently, a valid factory_bot definition(*) for a valid Ruby class. Good code? Probably not. Possible? For sure.

So we need to make sure this still works even if we add new functionality.

For that reason, I think we might need a new class.

(* I haven't tried it.)

Yes right didn't consider that, thanks for raising it!
here is another approach where I created FactoryBot::AttributeSequence class which encapsulates the proc so we can differentiate between a normal proc and an attribute sequence one
