When service register their policy rule oslo policy does not
copy the rule and instead work on the original object.
- bd9d47aa36/oslo_policy/policy.py (L1104)
policy enforcer modify the default rules in
_handle_deprecated_rule().
- bd9d47aa36/oslo_policy/policy.py (L767-L774)
In any case, oslo policy should make copy of the registered
rules.
Another thing it fix is setting of flag
RuleDefault._deprecated_rule_handled.
Flag _deprecated_rule_handled is set to True when
_handle_deprecated_rule() is called irrespective of it
actually handle the deprecated rule and add it in OR checks.
We should set this flag when acutally deprecated rule is
handled so that if any condition change like config flag or
file rules we correctly handle deprecated rules.
