Public bug reported:

While we attempted to update the default policy file in
https://review.opendev.org/c/openstack/oslo.policy/+/929714 , we
observed the glance-api can't start and complains the error below.

```
Traceback (most recent call last):
  File "/opt/stack/data/venv/bin/glance-wsgi-api", line 6, in <module>
    from glance.common.wsgi_app import init_app
  File "/opt/stack/glance/glance/common/wsgi_app.py", line 24, in <module>
    from glance.common import config
  File "/opt/stack/glance/glance/common/config.py", line 643, in <module>
    policy.Enforcer(CONF)
  File "/opt/stack/oslo.policy/oslo_policy/policy.py", line 543, in __init__
    self.policy_file = policy_file or pick_default_policy_file(
  File "/opt/stack/oslo.policy/oslo_policy/policy.py", line 378, in pick_default_policy_file
    if conf.find_file(conf.oslo_policy.policy_file):
  File "/opt/stack/data/venv/lib/python3.10/site-packages/oslo_config/cfg.py", line 2782, in find_file
Traceback (most recent call last):

    raise NotInitializedError()
oslo_config.cfg.NotInitializedError: call expression on parser has not been invoked
```

The problem here is that Enforcer() is called directly at the module
level in glance.common.config and we can't guarantee the module is
imported after CONF instance is initialized.
