The priority wasn't being passed from ActiveJob to Backburner, despite
priority being supported. This also brings it inline with the docs,
which mark Backburner as supporting priorities in the "Backend Features"
table: https://api.rubyonrails.org/classes/ActiveJob/QueueAdapters.html

If the `:queue` option is specified, then only the job(s) enqueued to
a specific queue will be performed.

Example:
```
def test_perform_enqueued_jobs_with_queue
  perform_enqueued_jobs queue: :some_queue do
    MyJob.set(queue: :some_queue).perform_later(1, 2, 3) # will be performed
    HelloJob.set(queue: :other_queue).perform_later(1, 2, 3) # will not be performed
  end
  assert_performed_jobs 1
end
```

Follow up #33265

[bogdanvlviv & Jeremy Daer]

http links will be redirected to the https version, but still better to
just directly link to the https version.

Reasons are that the Qu gem wasn't compatible since Rails 5.1,
gem development was stopped in 2014 and maintainers have
confirmed its demise. See issue #32273

* I think it's better to have a leading space after the `#`
  denoting the start of the comment.

ActiveJob wraps every adapter into its own class, that is later passed
into DelayedJob which is responsible for displaying all the logs.

This change improves the logging so we can easily trace executed
jobs and see meaningful information in the logs.

This reverts commit 3420a145, reversing
changes made to afb66a5a.

Refactored ActiveJob TestAdapter

Updated ActiveJob changelog

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.

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

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

This PR includes two changes for 2.0.0:

- Breaking API change around `async.perform` --> `perform_async`
- New addition of `perform_in`, which now allows end users of the
  adapter to use the `enqueued_at` public API method.

we are using `@monitor = Monitor.new` that inherit from Monitor class, we leave behind this commit https://github.com/rails/rails/commit/cbfc8b36

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.

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.

Partly fixes #18821
Signed-off-by: NJeroen van Baarsen <jeroenvanbaarsen@gmail.com>

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

fix error message

change raise to use rails conventions

fix misspells

Sidekiq logs the name of the job class being performed.  Because
ActiveJob wraps the class, this means every job logs as an AJ::JobWrapper
instead of the actual class name.

Will help fix mperham/sidekiq#2248

Since `ActiveJob::TestHelper` globally sets
`ActiveJob::Base.queue_adapter` on setup, there is no benefit in
instantiating a new `TestAdapter` per tests. The original rationale was
to allow parallel tests to run without interference, but since they'd
all mutate the global `ActiveJob::Base.queue_adapter`, that was never
realized.
