Replace yaml scopes by regular standards

[mbuechse]

Resolves #1198

This is meant as a preview of a quite radical change. It's possible that multiple PRs would be needed to be in line with extant regulations.

Any clue why the link checks are failing here?

[mbuechse]

@jklare Not really. The links do work. Maybe the docs page is defending itself against bots :)

LGTM, thanks for pushing this. I think this is a lot easier to understand when trying to figure out which tests need to pass and what the difference between each of the scope version is. I added a couple of questions and comments.

LGTM, let's get this merged. Since I am unsure if you want this to be squashed as one big things or separate commits, I will leave the honours to you @mbuechse :)

[jklare]

This should probably be rebased before being merged.

Unfortunately, we did not consider that the links to the old Scope pages are no longer available and therefore result in a 404 error.

• https://docs.scs.community/standards/scs-compatible-kaas/

I can update the links on https://sovereigncloudstack.org. However, I have used these URLs in numerous places over the past few months and have also shared them via email etc. which I cannot or do not want to change.

Since I am a supporter of "Cool URIs don’t change", I will try to fix this with "plugin-client-redirects" to redirect the old links to the new ones.
