This moves the code used for processing commits from GitPushService to
its own Sidekiq worker: ProcessCommitWorker.

Using a Sidekiq worker allows us to process multiple commits in
parallel. This in turn will lead to issues being closed faster and cross
references being created faster. Furthermore by isolating this code into
a separate class it's easier to test and maintain the code.

The new worker also ensures it can efficiently check which issues can be
closed, without having to run numerous SQL queries for every issue.

This class can be used to reduce a list of issues down to a subset based
on user permissions. This class operates in such a way that it can
reduce issues using as few queries as possible, if any at all.

This method returns the project's ID, making ExternalIssue slightly more
compatible with Issue (which also defines the "project_id" method).

This method can be used to retrieve a list of projects for a user that
said user has reporter access to. This list is then be reduced down to
a specific set of projects. This allows you to reduce a list of projects
to a list of projects you have reporter access to in an efficient
manner.

Closes #23026

change build list height to show 6,5 builds + improve padding of list, with first/last child selectors

Moved most of the functions that contained "window.doSomething" that were located at:
- app/assets/javascripts/application.js
To the following file:
- app/assets/javascripts/lib/utils/common_utils.js

The functions listed here:
- window.ajaxGet
- window.split
- window.extractLast
- window.rstrip
- window.disableButtonIfEmptyField
- window.disableButtonIfAnyEmptyField
- window.sanitize
- window.unbindEvents
- window.shiftWindow

Now will be accessible from the "gl.utils" namespace

No matter which environment Gitlab was running as, the admin/logs view
always showed production.log. This commit selects the logfile based
on Rails.env.

- Rename ProductionLogger to EnvironmentLogger
- Make EnvironmentLogger logfile depend on env
- Update spinach test for log tabs
