[$] Containers as a recognized kernel object

Description:
The foundation of the design for containers in the kernel is that there
isn't one; there is no container abstraction that the kernel recognizes. Instead, the kernel provides a long list of components namespaces,
control groups, sandboxing mechanisms, and more along with a note that
says, in effect, "some assembly required". There have been attempts ( repeatedly ) over the years to turn containers
into first-class objects with kernel support, but they have never gotten
far. Now Josef Bacik is making a
try with a concept that he calls "cells".
