Redact SQL in errors

* 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 86aa8f8c.

`atomic_write`: Ensure correct permission when `tmpdir` is the same as `dirname`.

Move `ActiveRecord::StatementInvalid` SQL to error property.
Also add bindings as an error property.

Sometimes `test_scaffold_tests_pass_by_default` test fails in CI.
https://travis-ci.org/rails/rails/jobs/457621750#L2095-L2120
It seems `manifest.json` was broken.

`webpacker` will compile automatically if packs is not compiled.
If parallel test is enabled, it seems that this compilation process is
executed simultaneously in multiple processes, and it may become an
inconsistent state.
In order to avoid this, compile before running the test.

This fixes following warnings:

```
test/dependencies_test.rb:287: warning: possibly useless use of :: in void context
test/dependencies_test.rb:300: warning: possibly useless use of a constant in void context

Fix ActionMailer assertion not working for mail defining delivery_job:

- If a Mail defines a custom delivery_job, all ActionMailer assertion
  helper (assert_emails, assert_enqueued_emails ...) wouldn't work.

  ```ruby
    MyMailer < ApplicationMailer
      self.delivery_job = MyJob
    end

    # This assertion will fail
    assert_emails(1) do
      MyMailer.my_mail.deliver_later
    end

  This PR leverage the new ActiveJob feature that accepts Procs for the
  `only` keyword and check if the delivery job is one of ActionMailer
   registered ones.

- That feature is useful to enqueue or assert that jobs got enqueued
  or performed based on dynamic conditions.
  We will be able to leverage that feature to fix all ActionMailer
  assertion helper issue when a Mailer define a custom delivery job
  (see next commit).

Fix query cache for multiple connections

Add slice! method to ActiveModel::Errors

Expand documentation for Hash#slice!

Currently the query cache is only aware of one handler so once we added
multiple databases switching on the handler we broke query cache for
those reading connections.

While #34054 is the proper fix, that fix is not straight forward and I
want to make sure that the query cache isn't just broken for all other
connections not in the main handler.

Make connection handler per thread instead of per fiber

The connection handler was using the RuntimeRegistry which kind of
implies it's a per thread registry. But it's actually per fiber.

If you have an application that uses fibers and you're using multiple
databases, when you switch the connection handler to swap connections
new fibers running on the same thread used to get a different connection
id. This PR changes the code to actually use a thread so that we get
the same connection.

Fix handling of duplicates for `replace` on has_many-through

Fix typo in development_dependencies_install.md [ci skip]

Since #33449, `event.end = Time.now` is not used anymore and should use

We can't use `deprecate :end=` in definition time in this module due to
circular require in `active_support/deprecation/behaviors`.
