usermanager: Remove concept of global authz provider
Rationale:
- Removes a bunch of code!
- We don't have many cases where an actor is not bound to one of our hosts
- A notable exception is the admin shell, but if we ever attempt to lock those
sessions down, there is a load of other work that also has to be done. And
it's not clear if we would need a global authz provider for that anyway.
- Removes an extra edge case from the necessary mental model for operators
- Sessions that aren't bound to a host generally are anonymous or have an
alternative auth model (such as by IP addres).
- With the encapsulation now provided by util.roles, ad-hoc "detached roles"
can still be created anyway by code that needs them.
