Fix temp file being deleted after the request while importing a GitLab project

Fixes https://gitlab.com/gitlab-com/infrastructure/issues/151

In production, the temporary uploaded file is getting deleted straight after the request so the Sidekiq worker is unable to find it in `/tmp`

Also, improved erroring/logging of this situation.

See merge request !4894

Support for rendering/redacting multiple documents

See merge request !4828

This commit changes the way certain documents are rendered (currently
only Notes) and how documents are redacted. Previously both rendering
and redacting would run on a per document basis. The result of this was
that for every document we'd have to run countless queries just to
figure out if we could display a set of links or not.

This commit changes things around so that redacting Markdown documents
is no longer tied into the html-pipeline Gem. This in turn allows it to
redact multiple documents in a single pass, thus reducing the number of
queries needed.

In turn rendering issue/merge request notes has been adjusted to take
advantage of this new setup. Instead of rendering Markdown somewhere
deep down in a view the Markdown is rendered and redacted in the
controller (taking the current user and all that into account). This has
been done in such a way that the "markdown()" helper method can still be
used on its own.

This particular commit also paves the way for caching rendered HTML on
object level. Right now there's an accessor method Note#note_html which
is used for setting/getting the rendered HTML. Once we cache HTML on row
level we can simply change this field to be a column and call a "save"
whenever needed and we're pretty much done.

Fix tmp file being deleted after the request plus some cleanup and improved erroring for this situation

Fix settings_spec so that it can that run by itself

Running `spec/settings_spec.rb` would fail because it would attempt to load `1_settings.rb`, which would reference `Rails`. This constant was not loaded without `spec_helper.rb`.

Replace Haml with Hamlit

What this change does:
- It replaces HAML with [Hamlit](https://github.com/k0kubun/hamlit), a much more efficient implementation of HAML.
- It removes `haml-rails`.
- It adds `hamlit.rb` and removes `haml.rb`.
- It makes things faster and less memory-hungry!

See also #13201.

Mobile Safari.

Use jQuery objects in ref dropdown

## What does this MR do?

Keeps the behaviour the same as the ref dropdown, however it now uses jQuery objects to handle the HTML creation instead of passing strings around. It pretty much worked out the box so not much was changed in the dropdowns themselves. Will be easy to transfer this over to other dropdown menus as well.

## What does this MR do?

This MR adds basic documentation for the two Emoji Rake tasks.

These Rake tasks only had some small amount of source level documentation.

This commit eager loads the award emoji on both the issues and the MRs.
When loading an issue with 108 comments this reduces the query count by
327 queries. On a merge request with the same amount of comments this
saves 148 queries. The large difference is not clear to me at this
point and the total query count is still huge with 387 and 1034
respectively. The biggest problem however, remains the calculation of
participants.

Fix user creation with stronger minimum password requirements

## What does this MR do?

`doc/security/password_length_limits.md` Describes a way to increase minimum requirements of passwords, via `config/initializers/devise_password_length.rb`. However, user creation hardcoded password generation at 8 characters.

If the minimum was set at any more than 8 characters, user creation will fail.

Function now looks up minimum length requirement.

## What are the relevant issue numbers?

Fixes #14563.
