Title:
  "admin"-ness not properly scoped

Status in Cinder:
  Fix Released
Status in Glance:
  New
Status in OpenStack Dashboard (Horizon):
  Fix Released
Status in Keystone:
  Confirmed
Status in neutron:

Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  Fact: Keystone's rbac model grants roles to users on specific tenants,
  and post-keystone redux, there are no longer "global" roles.

  Problem: Granting a user an "admin" role on ANY tenant grants them
  unlimited "admin"-ness throughout the system because there is no
  differentiation between a scoped "admin"-ness and a global
  "admin"-ness.

  I don't have a specific solution to advocate, but being an admin on
  *any* tenant simply *cannot* allow you to administer all of keystone.

  Steps to reproduce (from Horizon, though you could do this with the
  CLI, too):

  1. User A (existing admin) creates Project B and User B.
  2. User A adds User B to Project B with the admin role on Project B.
  3. User B logs in and now has unlimited admin rights not only to view things in the dashboard, but to take actions like creating new projects and users, managing existing projects and users, etc.
