The /etc/$APP/policy.json  controls what users are allowed to do for $APP. For example, /etc/nova/policy.json controls this for nova, /etc/glance/policy.json controls glance. (I think swift uses a different scheme).

If you want to restrict users from doing things in nova, you need to create a role in keystone and then modify /etc/nova/policy.json so that this role is required for nova operations. 

For example, you could create a role called "novauser", and then  /etc/nova/policy.json to require that role for every operation. I think it would look like this (haven't tried this myself):
