Quarantine: Update failure issue link

This style change enforces `return if ...` instead of
`return nil if ...` to save maintainers a few minor review points

The documentations only covered the percentage based feature gates.
These don't work really well for a number of reasons, for example; a new
visual element in GitLab would be weird to see only 25% of the time.

Allowing feature gates based on projects and groups has been supported,
now it's documented.

CE backport of ee-parallel-diff-view

See merge request gitlab-org/gitlab-ce!25734

With this we allow authentication using a session or using personal
access token.

Authentication using a session, and CSRF token makes it easy to play
with GraphQL from the Graphiql endpoint we expose.

But we cannot enforce CSRF validity, otherwise authentication for
regular API clients would fail when they use personal access tokens to
authenticate.

Re-add gitlab:ui:visual ci job

Closes gitlab-ui#192

See merge request gitlab-org/gitlab-ce!25808

These adjustments make sure our GraphQL helpers support rendering
queries for empty fields like this:

      {
        echo(text: "Hello world")
      }

Instead of like this:

     {
       echo(text: "Hello world") {
       }
     }

The latter would be an invalid query, causing parsing errors.
