Decouple base elements from kernel

[dhruvkb]

The mission is to extract all such elements as root Model and root ModelSerializer into a Formula 1 of the backend. This would allow other services to import such elements from Formula 1 instead of the kernel which must change really rarely in production due to delicate swappable models.

This is a long, tedious and complicated task so long-term dedication is a must before taking this on.
