Correct me if I'm wrong, but it seems to me that the problem is simply
that the default policy used in keystone and nova says that "admin is
anybody with role `admin' on any tenant", as you can see in their
respective policy.json files.
I think that this rule should probably be set to something else by
default, like the user is admin if "it has role admin on a specific
tenant (like a tenant named `admin')". Tthat would allow to emulate the
old "global" admin role, just by using a specific tenant.
