[ACTION] Organize better the design document

[AntonioDiTuri]

A proposal for a better organization of the design document will follow shortly in the next days

At this point, we should move as much info as possible to this repo and decommission the design doc. It is out of date and hard to maintain and this adds to confusion. But we still need a way to onboard people and have up-to-date documentation.

As you suggested, we can create new Google docs for ad hoc design documents in the future.

Thinking on this more, it would be an important piece of what we deliver by KubeCon, since it would make it possible for us to share the work and onboard new contributors.

BONUS POINTS: create a website to host these docs!

This has mostly been addressed:

• Added a note to the design doc that it's out of date
• Removed mentions to the design doc
• Started initiatives to re-write sections as proposals
