[keystone] [SOLVED] is_admin_project=true although no admin project configured

I found that Ussuri implements the old behaviour by default, and the new 
behaviour must be configured with

enforce_scope = true
enforce_new_defaults = true

in each service configuration file (I have not checked whether services 
other than Keystone and Nova observe these new oslo_policy settings).
