Nova antelope release has enabled the RBAC new defaults
by default
- https://review.opendev.org/c/openstack/nova/+/866218
With the latest release of Nova have new defaults enable,
we should test the same by default in devstack. This change
make NOVA_ENFORCE_SCOPE flag to True by default so that every
job will run with Nova new defaults.
As old defaults are still supported (in deprecated way), we will keep
NOVA_ENFORCE_SCOPE flag so that we can have a single job can disable
the new defaults and continue testing the old defaults.
