IRegistrationStack
A stack of registrations for a set of parameters
A service will have a registry containing registry stacks
for specific parameters. For example, an adapter service will
have a registry stack for each given used-for and provided
interface.
The registry stack works like a stack: the first element is
active; when it is removed, the element after it is automatically
activated. An explicit None may be present (at most once) to
signal that nothing is active. To deactivate an element, it is
moved to the end.
