Create release notes (a.k.a CHANGELOG) for Drupal 8.4.0-alpha1 and Drupal 8.4.0

Here's a better draft outline for the release notes with some tricky things explained (but most issues still missing). FWIW, I'm editing this in https://github.com/xjm/drupal_core_release/blob/master/templates/CHANGEL... (a github repository we use for automating release processes).

This adds the markdown format to the CHANGELOG file for now. We won't necessarily actually ship it this way; the past changelog is probably going to be removed and instead kept in a handbook page on d.o. However, I thought it would be easier to provide interdiffs this way.

Actually attaching the patch.

@gnuget, yep for sure! I've added the "8.4.0 release notes" tag to that issue. Would you like to add an entry to the patch here for it under the third-party libraries section?

Thanks @gnuget!

For IFE, @andrewmacpherson suggested we draw on #2888189: Update hook_help and DO docs for Inline Form Errors.

Adding a couple more stub sections, and improving the sections on Media and Datetime Range.

Phooey, named interdiff as a patch. Sorry testbot.

A few more textual improvements for Media.

Here's stub markdown for the issues that are already tagged but not yet included in the patch:

(These issues are tagged for the release notes, but still open. Some issues might be tagged to highlight a certain outstanding bug in the release notes. Others might have been reopened for a backport or followup. Some might have been tagged prematurely or incorrectly. Check the issue carefully, and if appropriate, move these bullets into the appropriate sections above and draft more descriptive text. Check with a release manager if you are unsure.)

Thanks @mpdonadio!

We also should add a similar mention for media (from #2835767: Media + REST: comprehensive test coverage for Media + MediaType entity types). Probably:

Similarly, the REST API for Media is not final and support for decoupled applications will be improved in a future release.

For this issue:
[Drush 8.x doesn't install Drupal 8.4.x and Drush master doesn't install Drupal 8.3.x](https://www.drupal.org/node/2874827)

It's already addressed by the first section of the release notes; we just need to link it.

Thanks everyone!

I untagged this one, because I don't think it's quite important enough for a release notes mention. The CR should be sufficient. So we can remove it here as well.

Oh @dawehner, I agree in general that we should only mention the important issues. If there are any that seem not worth mentioning, could you highlight those? Then we can either untag them, or better explain their significance.

At least for me CHANGELOG.txt seems to be a high level overview, rather a list of change records. Maybe a general paragraph like:

For a list of API changes/additions, please have a look at the change records.
Here is a list of stuff which is a bit meh.

Yes, the release notes always include this. Those standard paragraphs are not included in the draft here but will be in the release notes themselves.

* Options in timezones selector [are now grouped by regions](https://www.drupal.org/node/2847651)
+  and represent cities instead of timezone names.

This feels like a minor change, but maybe I'm totally wrong.

For this one, the usability and accessibility contributors involved were very excited about this change, so that seems reason to include it I guess.

I'll ask the people who tagged the other issues to weigh in on why they proposed them for inclusion. Thanks!

Oh on this one:
+* (open) [#2885368: Config export key order for sequences: "orderedby" does not support cases where the order actually matters](https://www.drupal.org/node/2885368)

See #26.3; it's included because it's a pending followup related to an important config change. So it's not going to be mentioned on its own.

For my and others' convenience, here are the remaining issues we're discussing whether to untag:

1. #2827084: EntityNormalizer::denormalize should not throw UnexpectedValueException, but \Symfony\Component\HttpKernel\Exception\UnprocessableEntityHttpException, so we get a 422 response instead of 400 tagged by alexpott

5. #2872611: Optimise \Drupal\Core\Extension\ThemeHandler::refreshInfo() for the early installer un-backported critical and should go under the "important bugfixes" section.
6. #2403703: Allow field types to enforce the cardinality tagged by alexpott
7. #2472337: Provide a lazy alternative to service collectors which just detects service IDs tagged by effulgentsia:

9. #2705037: Asset library DX: Non-helpful fatal error if CSS isn't nested under an existing category tagged by Wim Leers:

We're iterating on these in real time in a Google doc. We'll resume this issue for 8.4.0 after the alpha ships. Thanks everyone!

Alright, the attached is the result of hours of work by @prestonso, @webchick, and myself. I've proofread all but the following sections:

## REST and API-first improvements
## Performance and scalability improvements
## Developer experience improvements
## Automated testing improvements
## Third-party library updates
### Migrate Drupal and Migrate Drupal UI

No interdiff since we changed pretty much every line in one way or another.

/facepalm

For both Workflows and Content Moderation, we should add a section like:

"This module has significant backwards compatbility and data model breaks from early experimental versions. (As experimental modules, they do not officially require a a stable data model or backwards-compatible APIs.) However, unnofficial upgrade paths are available in #2890187: [META] Unofficial content_moderation upgrade path. Now that both these modules in beta, after 8.4.0-beta1 with its final breaks, users can expect backwards compatibility and officially supported upgrade paths from now on.

Oh and it still needs review for accuracy and clarity, especially the sections I listed in my comment in #50.

Okay, here's the finalish version we're using for the alpha.

If you have additions to make as we go through the beta and RC toward 8.4.0, please make sure the issue is tagged with "8.4.0 release notes" and feel free to add your additions here!

Yes, that's because I committed it.

Thanks @jibran; I spent a bunch of time trying to get a good git command but never found one that worked quite as needed. I'll check that one out.

For the changelog, I don't think we need to commit an update until the minor. Committing the initial draft for the alpha was just an experiment.

However, we could definitely use subject matter experts' help supplying patches on this issue to add to it with additional improvements since alpha1!

Here's the issues that are tagged but not yet included in #68:

   It should be hyphenated as "backwards-incompatible", but maybe we could be more direct and say "backwards compatibility breaks from Drupal 8.3.x". And in addition to the upgrade path, maybe we can link them something that shows what the BC breaks are? I imagine it's some list of change records. Also, maybe we should move this paragraph to above the list of specific improvements as it's pretty important information.

Fail looks like https://www.drupal.org/node/2806697 again.

## Unlisted open issues

(These issues are tagged for the release notes, but still open. Some issues might be tagged to highlight a certain outstanding bug in the release notes. Others might have been reopened for a backport or followup. Some might have been tagged prematurely or incorrectly. Check the issue carefully, and if appropriate, move these bullets into the appropriate sections above and draft more descriptive text. Check with a release manager if you are unsure.)

* [Update CKEditor library to 4.7.3](https://www.drupal.org/node/2908864)

• I agree that we don't need to mention #2901626: CSS animations cause \Drupal\Tests\outside_in\FunctionalJavascript\OutsideInBlockFormTest random fails and #2902191: Determine cause and fix random fail in \Drupal\Tests\settings_tray\FunctionalJavascript\SettingsTrayBlockFormTest::testBlocks; we usually exclude random test fail issues from the monthly release notes.
• I agree also on skipping #2900687: Fatal error when saving a node type without content moderation; it was worth mentioning in the beta since it resolved a pre-release regression, but not worth mentioning after that.
• So that leaves the several Migrate issues and #2907654: No URL can be generated for the 'add-form' route of EntityViewMode and EntityFormMode entities for criticals.
• I'm going to untag #2908864: Update CKEditor library to 4.7.3 since we are in commit freeze now.

Making some edits.

Attached:

• Incorporates some of the missing items.
• Updates the "known issues" section from changes added since the alpha.
• Removes a couple issues I untagged.
• Rewraps some lines.

There are still a couple marked with @todo and others missing. We probably also should still remove some of the unneeded items for Migrate and Settings Tray in particular since both are quite long.

Attached rewraps a lot more lines that were miswrapped with links (the closing ] for the text and the opening ( for the link need to be on the same line, but other than that they can wrap normally.

I also consolidated some more points on Migrate API changes and changed the remaining @todo bits into actual links.

Committed that since it made the interdiff basically unreadable. That still leaves all these:

* [Clearing cache via UI in translated language resets config translation of field labels to default language](https://www.drupal.org/node/2650434)
* [The Page Title block's title behaves in a confusing way with Settings Tray and the Help block incorrectly has Settings Tray styling](https://www.drupal.org/node/2782891)
* [Break BrowserTestBase & children dependency on Simpletest, deprecate stub BC traits](https://www.drupal.org/node/2803621)
* [BaseFieldOverride entities created by content_translation break content_moderation because they don't support computed fields](https://www.drupal.org/node/2848775)
* [Rewrite the 'Latest revision' views filter and remove the revision_tracker table](https://www.drupal.org/node/2865579)
* [Prevent enabling the media module if media_entity contrib 1.x is already enabled](https://www.drupal.org/node/2896427)

* [Again update non-Symfony dependencies in lock file before 8.4.0](https://www.drupal.org/node/2909743)

Alright, I summarized a bunch of Settings Tray fixes in a single paragraph, and then added in the rest as stubs.

Incorporating the bit about the media_entity contrib module.

Building off #91 and moving the revision_translation_affected issue up after the one that spawned it, since it's not in itself specific to Content Moderation.

All done. Thanks everyone!
