    Add variable override for OPENSTACK_KEYSTONE_ADMIN_ROLES
    
    As Horizon treats admins differently and can't discern what roles are
    administrative in nature, we have to tell it if there are roles
    beyond/besides "admin".
    
    If not overriden by the user, then the default is `['admin']` as seen
    in the code:
