Motivation:
- Currently we have 2 seperate monkey patches in place for tracking
enqueded time for 2 seperate workers. It seems that activejob could be
a source of truth for how long an item has been enqued so that we can
easily use it for consistent monitoring across workers/apps to ensure
that jobs are running at an acceptable speed.
Changes:
- Add an enqueded at attribute and serilization tooling.
- Add a method to get how long a job has been enqueded for.
- Add a logging item to show how long a job was enqued prior to the
perform method firing.

ActiveJob
Some adapters like Resque that use Redis, convert the Ruby hash with a
default value, Hash.new(0), into a regular hash without a default value
after serializing, storing and deserializing. This raises an error when
we try to access a missing exception key. A simple solution is not to
rely on the hash's default value, and provide a default as alternative
when accessing it instead.

* Keep executions for each specific declaration
Fixes #34337
ActiveJob used the global executions counter to control the number of
times a job should be retried. The problem with this approach was that
in case a job raised different exceptions during its executions they
weren't retried the number of times defined by their `attemps` number.
**Example:**
Having the following job:
```ruby
class BuggyJob < ActiveJob::Base
retry_on CustomException, attemps: 3
retry_on OtherException, attempts: 3
end
```
If the job raised `CustomException` in the first two executions and then
it raised `OtherException`, the job wasn't retried anymore because the
global executions counter was already indicating 3 attempts.
With this patch each `retry_on` declaration has its specific counter so
that the first two executions that raise `CustomException` don't affect
the retries count that future exceptions may have.
* Revert "clarifies documentation around the attempts arugment to retry_on"
This reverts commit 86aa8f8c5631f77ed9a208e5107003c01512133e.

My spellchecker flagged this as an incorrect spelling, upon further
research it appears to be a point of contention in English. Either way
might work.
After further examination queuing is much more common in the Rails
codebase so making this change will serve to standardize the spelling.

Using `included` to define `attr_acessor` and `attr_writer` is causing
these methods to not show up in the documentation.

When a job was just deserialized `arguments` is `nil` and the serialized
arguments are in the `@serialized_arguments` variable. If we try to
serialize this job again the arguments are going to be `nil` instead of
what was serialized.
The test we had was not checking this case because it was deserializing
the job in the same object that had the arguments.
To fix this, when the `@serialized_arguments` are present we return it
instead of the result of the `arguments` serialized.

Record what was the current timezone in effect when the job was
enqueued and then restore when the job is executed in same way
that the current locale is recorded and restored.

1) It seems that it raise error on example code in `ActiveJob::Core`.
Before:
```ruby
class DeliverWebhookJob < ActiveJob::Base
def serialize
super.merge('attempt_number' => (@attempt_number || 0) + 1)
end
def deserialize(job_data)
super
@attempt_number = job_data['attempt_number']
end
rescue_from(Timeout::Error) do |exception|
raise exception if @attempt_number > 5
retry_job(wait: 10)
end
def perform
raise Timeout::Error
end
end
```
Then it run `DeliverWebhookJob.perform_now` in `rails console`. And raise error:
NoMethodError: undefined method `>' for nil:NilClass
from /app/jobs/deliver_webhook_job.rb:12:in `block in <class:DeliverWebhookJob>'
So I thought it's necessary to fix it.
After:
```ruby
class DeliverWebhookJob < ActiveJob::Base
attr_writer :attempt_number
def attempt_number
@attempt_number ||= 0
end
def serialize
super.merge('attempt_number' => attempt_number + 1)
end
def deserialize(job_data)
super
self.attempt_number = job_data['attempt_number']
end
rescue_from(Timeout::Error) do |exception|
raise exception if attempt_number > 5
retry_job(wait: 10)
end
def perform
raise Timeout::Error
end
end
```
Then it run `DeliverWebhookJob.perform_now` in `rails console`. And it does'nt raise error NoMethodError.
2) Use `Timeout::Error` instead of `TimeoutError` (`TimeoutError` is deprecated).

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

Let’s do it when we actually execute instead. Then the tests dealing
with comparable serializations won’t fail either!

Placing non-native JSON data types, like symbols, in the hash to serialize means that the deserialize method will return something different from what was serialized, a common bug and source of frustration for devs.

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.

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

Indent the list content by 4 spaces instead of 2 to match the other
changelog files. Also wrap the lines around 80 chars.
Finally update the documentation example with nit-picky things.
