Fix bug where e-mails were not being sent out via Sidekiq

By default, ActionMailer uses the "mailers" queue, but this entry
was not included in the list of queues for Sidekiq to use.

Re-organize queues for EE

See merge request !815

Use separate queues for all Sidekiq workers

## What does this MR do?

This MR updates all workers so that they (mostly) use their own Sidekiq queues. This in turn allows us to monitor queues more accurately and in the future impose queue specific throttles, limits, etc.

This is a critical part we need in 8.13, despite it being so close to release day.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/23370 for more information.

Cache the last usage data to avoid unicorn timeouts

On GitLab.com, the usage data cache was never populated because it takes longer than 60 seconds to generate.

This MR also improves usage data performance. The Event default_scope was causing the query to use the wrong index, causing the query to scan through all rows unnecessarily.

Closes #1044

See merge request !779

Fixed compare ellipsis messing with layout

## What does this MR do?

Fixed a bug where the ellipsis would cause the form to mess with the layout.

Disable warming of the asset cache in Spinach tests under CI

I suspect some combination of Knapsack tests cause no regular Rack tests
to be loaded (i.e. all JavaScript tests), which leads to the error:

ArgumentError: rack-test requires a rack application, but none was given

In CI, we precompile all the assets so there is no need to warm the
asset cache in any case.

Closes #23613

Fix broken label uniqueness label migration

The previous implementation of the migration failed on staging because
the migration was attempted to remove labels from projects that did not
actually have duplicates. This occurred because the SQL query did not
account for the project ID when selecting the labels.

To replicate the problem:

1. Disable the uniqueness validation in app/models/label.rb.
2. Create a duplicate label "bug" in project A.
3. Create the same label in project B with label "bug".

The migration will attempt to remove the label in B even if there are no duplicates.

To fix the issue, include the project ID when selecting the labels.

Closes #23609

See merge request !7030

Use iid deployment refs

This fixes the 404, because `find_by` will return nil instead of throwing an error.

Fix GitLab project import when a user has access only to their default namespace

## What does this MR do?

It fixes a bug when a namespace ID was not passed to `/import/gitlab_project/new` page. It occurred when a user have no choice of the namespace, so we did not render the input for namespace ID. This MR introduces a hidden input for the described case.

Fixed issues with sticky mr tabs & sidebar

## What does this MR do?

- Fixes an issue where opening the sidebar wouldn't update the merge request tabs width & positioning
- Fixes issues when resizing the browser

Rather than updating the JS to react to different methods, this way allows the CSS to keep control of the positioning & sizes.

[Doc] Fix `ref` parameter name for `commits/statuses`

The attribute to filter by branch or tag needs to be named `ref`, not `ref_name`. And indeed the attribute in the JSON response is `ref` (and not `ref_name`).

# Tasks

- [ ]  ee#675 !645 Restrict pushes/merges to specific groups
    - [x]  Implementation
        - [x]  Basic model-level implementation
        - [x]  Test / refactor
        - [x]  Rudimentary frontend (controller actions + autocomplete for the dropdown)
            - [x]  Groups that a project hasn't been shared with can't be selected
        - [x]  Look for edge cases
    - [x]  Questions
        - [x]  What are LDAP group links?
            - A GitLab group can be synced with one or more LDAP groups
            - The sync happens in an async task, an the LDAP group users are _imported_ into the GitLab group
            - `group.users` on a GitLab group returns the LDAP group users as well (after the import task has run)
            - We check `group.users` for this feature, so we shouldn't need any additional work to support LDAP groups
    - [x]  CHANGELOG
    - [x]  Removing a group should remove the access
    - [x]  `autocomplete/groups` issue
    - [x]  Fix uniqueness validation
    - [x]  Assign to @alfredo1 for UI work
    - [x]  Wait for !581 to be merged
