This change introduces the notion of "Stack subclassing" in two ways:
1. A Stack may declare that it subclasses another one using the base property:
name: mystack
base: other/stack
.. as before ..
2. A Stack may declare that it is abstract; in other words, that it is meant
solely for subclassing, and cannot be compiled and deployed independently:
name: mystack
abstract: true
.. as before ..
Note that non-abstract Stacks are required to declare at least one Service,
whether that is public, private, or both.
