The `ActiveJob::TestHelper` replace the adapter to test adapter in
`before_setup`. It gets the target class using the `descendants`, but if
the test target job class is not loaded, will not be a replacement of
the adapter.
Therefore, instead of replacing with `before_setup`, modified to
replace when setting adapter.

Fixes #26360

Refactored ActiveJob TestAdapter

Updated ActiveJob changelog

Fixed typo in changelog

Fixed formatting issue in changelog

If the deadlock has occurred `ActiveRecord::Deadlocked` will raise.
Ref: #25107, #26059

This will fix issues in [resque-scheduler](https://github.com/resque/resque-scheduler) `#job_to_hash` method,
so we can use `#enqueue_delayed_selection`, `#remove_delayed` method in resque-scheduler smoothly.

Yield the job instance so you have access to things like `job.arguments` on the custom logic after retries fail

Active Job: Add note about ability to configure adapters on per job basis in CHANGELOG and release notes.

Use one shared worker pool for all queues with 0-#CPU workers rather
than separate pools per queue with 2-10*#CPU workers each.

Adds changelog headers for beta3 release

During the `5.0.0.beta1` release, the CHANGELOGs got an entry like the
following:

```
* No changes.
```

It is kinda confusing as there are indeed changes after it. Not a
biggie, just a small pass over the CHANGELOGs.

The latest, currently unreleased, version of queue_classic is required
for this to work. See
https://github.com/QueueClassic/queue_classic/pull/262 for more details.

When `#perform_later` is called the locale isn't stored on the
queue, which results in a locale reset when the job is performed.

An example of the problem:

    I18n.locale = 'de'
    HelloJob.perform_now # german message, correct

but

    I18n.locale = 'de'
    HelloJob.perform_later # english message, incorrect

This PR attaches the current I18n.locale to every job during the
serialization process. It is then restored during deserialization
and used to perform the job with the correct locale.

It falls back to the default locale if no serialized locale is
found in order to provide backward compatibility with previously
stored jobs. It is not necessary to clear the queue for the update.

Further work to provide provider_job_id for queue adapters.

When a job is added to Sidekiq by ActiveJob, make sure we still can get the
original job_id provider by Sidekiq. We do this by adding the sidekiq jid to
provider_job_id field on the job object.

When queueing with DelayedJob, get the id of the job instance and report
it back to ActiveJob as provider_job_id.

type.

This allows specific jobs to be tested, while preventing others from
being performed unnecessarily.

Example:

    def test_hello_job
      assert_performed_jobs 1, only: HelloJob do
        HelloJob.perform_later('jeremy')
        LoggingJob.perform_later
      end
    end

An array may also be specified, to support testing multiple jobs.

Example:

    def test_hello_and_logging_jobs
      assert_nothing_raised do
        assert_performed_jobs 2, only: [HelloJob, LoggingJob] do
          HelloJob.perform_later('jeremy')
          LoggingJob.perform_later('stewie')
          RescueJob.perform_later('david')
        end
      end
    end

Fixes #18802.

Trim space and document :only option.

Unfortunately, the HashWithIndifferent access approach is insufficient
for our needs. It's perfectly reasonable to want to use keyword
arguments with Active Job, which we will see as a symbol keyed hash. For
Ruby to convert this back to keyword arguments, it must deserialize to a
symbol keyed hash.

There are two primary changes to the serialization behavior. We first
treat a HWIA separately, and mark it as such so we can convert it back
into a HWIA during deserialization.

For normal hashes, we keep a list of all symbol keys, and convert them
back to symbol keys after deserialization.

Fixes #18741.
