cleanup noauth path

- we don't need to set keystone_authtoken values
- setting OS_AUTH_TYPE breaks all other clients since it's global
  so just leave it and let user set to client specifically. this
  will not make integration gate work with noauth as there are other
  commands which require gnocchi to be registered in catalog
