Subject: Parameterized mailers can configure delivery job

Setting parameterized_delivery_job on a mailer class will cause Parameterized::MessageDelivery to use
the specified job instead of ActionMailer::Parameterized::DeliveryJob:

    class MyMailer < ApplicationMailer
      self.parameterized_delivery_job = MyCustomDeliveryJob
      ...
    end
