If admins decreased the maximum filesize limit the ActiveRecord
validations would fail.

FEATURE: Show a placeholder instead of videos in preview (#10962)
Adding a video in composer and then continuing to type into it will make the
video element flicker and restart playback on every keystroke, as the preview
is rendered. In certain configurations, this can lead to some performance
problems too.

Onebox already does the same for external videos.

b3b9cf7c5d REFACTOR: New format for acceptance tests
This gets us closer to how newer Ember versions want to do things, but
with a bit of Discourse flair.

`acceptance` now takes a function as a parameter, and tests need to be
declared in that new function context.

A new helper, `needs`, is passed as a parameter. You can use it to set
up the test the way you want.

FIX: Ensure slow mode duration is correctly edited and displayed. (#10945)
* FIX: Ensure slow mode duration is correctly edited and displayed.

This commit fixes a bug where you were forced to set hours, minutes, and seconds or you won't be able to set the slow mode. Also, the duration was not displayed correctly due to the seconds not being truncated.

Additionally, we'll always display the hours, minutes, and seconds inputs for clarity and remove the blue banner.

* Set slow mode modal tweaks.

Uses labels instead of placeholders.
Input fields only visible when custom option selected.
Replace "Custom Duration" with "Pick Duration".

Additionally, place the `Set slow mode` button at the bottom of the topic actions menu.

* Perform the slow_mode validation also on the client-side before saving trying to save the post. This way, the post won't be staged.

FIX: calculate page if page param is not given to TopicView (#10953)
Currently, when page param is not given to TopicView we calculate page for canonical_path, however, it is skipped for next_path.

We should use the same calculation to define page, so next page URL will be accurate. Currently if you [view source of meta post](view-source:https://meta.discourse.org/t/post-rate-limit-trigger-for-a-topic-thats-heating-up/98294/46) you will see:

b460a6d059 REFACTOR: Continue to converge on what Ember CLI wants us to do
* The creation of a testing div is specific to Rails, so that is
moved back out of setupTests();

* We've removed the `Discourse` globals from the acceptance helpers in favor of
`setApplication`/`getApplication`.

* We pass the container to setupTests because there is no
`__container__` in later Ember versions.

* `App` is now `app` because it's not a constant or class, it's an
instance of an application.

PERF: Disable Sidekiq only during database restore (#10857)
It pauses Sidekiq, clears Redis (namespaced to the current site), clears Sidekiq jobs for the current site, restores the database and unpauses Sidekiq. Previously it stayed paused until the end of the restore.

Redis is cleared because we don't want any old data lying around (e.g. old Sidekiq jobs). Most data in Redis is prefixed with the name of the multisite, but Sidekiq jobs in a multisite are all stored in the same keys. So, deleting those jobs requires a little bit more logic.

Dependency on gifsicle, allow_animated_avatars and allow_animated_thumbnails
site settings were all removed. Animated GIF images are still allowed, but
the generated optimized images are no longer animated for those (which were
used for avatars and thumbnails).

The added 'animated' is populated by extracting information using FastImage.
This field was used to selectively reoptimize old animations. This process
happens in the background.

PERF: don't ask for new posts while loading new posts (#10937)
Previous to this change we had no protection to ensure we wait on a request
for more posts prior starting another request.

In outlier cases if 10 people post at the same time on a topic a flood of
requests could start.

To improve this situation we now ensure that we are done asking for new posts
prior to asking for the next batch.

Also addresses some style issues raised previously and moves init to top
of class.

FEATURE: when we fail to ship topic timings attempt to retry (#10916)
* FEATURE: when we fail to ship topic timings attempt to retry

This change amends it so

1. Topic timings are treated as background requests and subject to more
 aggressive rate limits.

2. If we notice an error when we ship timings we back off exponentially

The commit allows 405, 429, 500, 501, 502, 503 and 504 errors to be retried.

500+ errors usually happen when self hosters are rebuilding or some other
weird condition.

405 happens when site is in readonly.
429 happens when user is rate limited.

The retry cadence is hardcoded in AJAX_FAILURE_DELAYS, longest delay is
40 seconds, we may consider enlarging it.

After the last delay passes we give up and do not write timings to the
server.

* Address feedback

- Omit promise, no need to use promises in sendNextConsolidatedTiming
- Correct issue where >= -1 was used and > -1 was intended
- Use objects for consolidated timings instead of Array
- Stop using shift/unshift and instead use push / pop which are faster

* Move consolidated timing initialization to constructor

* Remove TODO and just console.warn if we have an issue

in duplicate and confusing lines in the release notes.
