Discuss - enable the pipeline editor for .gitlab-ci.yml by default

This issue was opened in light of the discussion in slack where @kencjohnston had asked

Why do we display the “Edit” (takes you to modified single-file editor) - link when viewing the .gitlab-ci.yaml file in the repository view? There isn’t anything that view does that isn’t better in the Pipeline Editor. I think we should remove it.

Why should we make the pipeline editor the default experience?

• Editor is your one-stop-shop for CI, it has a rich feature set that improves the user experience
• It is planned to be the default editor (eventually) - so maybe now is the time to do so?
• Majority of our users use it already (85% use the editor 10% the single file editor 5% web-ide)

Why should we not make it the default experience

• It is still missing the preview changes feature

@gitlab-com/pipeline-authoring-group I would love to hear your opinion
