- ### Problem

  ```ruby
    MyJob < ApplicationJob
      before_enqueue { throw(:abort) }
      after_enqueue { # enters here }
    end
  ```
  I find AJ behaviour on after_enqueue and after_perform callbacks
  weird as they get run even when the callback chain is halted.
  It's counter intuitive to run the after_enqueue callbacks even
  though the job wasn't event enqueued.

  ### Solution

  In Rails 6.2, I propose to make the new behaviour the default
  and stop running after callbacks when the chain is halted.
  For application that wants this behaviour now or in 6.1
  they can do so by adding the `config.active_job.skip_after_callbacks_if_terminated = true`
  in their configuration file.

Fix ActiveJob logging when callback chain is halted:

- ### Problem

  ActiveJob will always log "Enqueued MyJob (Job ID) ..." even
  if the job doesn't get enqueued through the adapter.
  Same problem happens when performing a Job, "Performed MyJob (Job ID) ..." will be logged even when job wasn't performed at all.
  This situation can happen either if the callback chain is terminated
  (before_enqueue throwing an `abort`) or if an exception is raised.

  ### Solution

  Check if the callback chain is aborted/exception is raised, and  log accordingly.

Bring back feature that allows loading external route files:

= This feature existed back in 2012 https://github.com/rails/rails/commit/5e7d6bba79393de0279917f93b82f3b7b176f4b5
  but got reverted with the incentive that there was a better approach.
  After discussions, we agreed that it's a useful feature for apps
  that have a really large set of routes.

I added myself links to the Ruby on Rails Tutorial years ago, after
meeting Michael in a RailsConf.

By then, the book was a commercial product, but had a free online
version and I thought it could be a good resource complementing the
official documentation.

Nowadays, only a few sample chapters are available for free, and I
don't consider these links to be fair with the rest of commercial
books about Rails anymore.

Revert "Use `app.config.file_watcher` for watcher in `RoutesReloader`"

This reverts commit 28e44f47.

A limitation of Listen is that it currently only supports watching directories.
Therefore, watching `config/routes.rb` will end up watching the entire `config` directory
if we use the evented file watcher. This causes problems especially if symlinks are present
in the `config` directory.

system tests: properly set driver options for non-headless drivers
