*   Make Active Job transaction aware when used conjointly with Active Record.

    A common mistake with Active Job is to enqueue jobs from inside a transaction,
    causing them to potentially be picked and ran by another process, before the
    transaction is committed, which may result in various errors.

    ```ruby
    Topic.transaction do
      topic = Topic.create(...)
      NewTopicNotificationJob.perform_later(topic)
    end
    ```

    Now Active Job will automatically defer the enqueuing to after the transaction is committed,
    and drop the job if the transaction is rolled back.

    Various queue implementations can choose to disable this behavior, and users can disable it,
    or force it on a per job basis:

    ```ruby
    class NewTopicNotificationJob < ApplicationJob
      self.enqueue_after_transaction_commit = :never # or `:always` or `:default`
    end
    ```
