Code Quality no 'Download' option and 'Keep' results in 404

Summary

When using artifacts:reports:codequality the resulting job has no ability to download the report and due to gitlab-org/gitlab-ee#4189 there is no way to view it. There is a 'Keep' button but clicking this results in a 404.

Steps to reproduce

1. Use the Jobs/Code-Quality.gitlab-ci.yml job within a pipeline. This has artifacts:reports:codequality set.
2. Run pipeline,
3. Navigate to the code_quality job and observe right hand panel.

Proposal

Going forward the Keep button will not be necessary after completion of #16267 (closed) and so will be removed.

The Download button will now download the codeclimate generated code climate report will then be available until the expire_in has passed and the download button should be made inactive.

Another issue was opened to improve the experience when no buttons are present but the job created one.
