Migrate to override_role for identity module (part 2)
Now that override_role has supplanted switch_role (which has
been deprecated) in [0], the RBAC tests need to switch to use
override_role.
This PS switches to override_role for the identity module. This
PS handles the last 10 modules for identity.
This PS also removes unnecessary indexing into response bodies.
