This reverts commit cb10b725c8929b8b4460f89c9d96c773af39ba6b.

https://gitlab.com/gitlab-org/gitlab-ce/issues/24007

Right now this is a no-op. We're going to add it as a trait argument to
all existing usages of the `:project` factory, so that later we can flip
`:empty_project` to just be `:project`, forcing developers to opt-in to
the slower option when their tests truly require it.

The button allows to choose a ".gitlab-ci.yml" template that automatically
sets up the deployment of an application.
The currently supported template is Kubernetes template.

Ensure external users are not able to clone disabled repositories.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/23788

This commit adds a number of _html columns and, with the exception of Note,
starts updating them whenever the content of their partner fields changes.

Note has a collision with the note_html attr_accessor; that will be fixed later

A background worker for clearing these cache columns is also introduced - use
`rake cache:clear` to set it off. You can clear the database or Redis caches
separately by running `rake cache:clear:db` or `rake cache:clear:redis`,
respectively.

# Conflicts:

In 8278b763 the default behaviour of annotation
has changes, which was causing a lot of noise in diffs. We decided in #17382
that it is better to get rid of the whole annotate gem, and instead let people
look at schema.rb for the columns in a table.

Fixes: #17382

Mostly replaces several Spinach tests with RSpec Feature tests.
