stx/update zuul broken by sysinv code change

[Al Bailey]

Brief Description
-----------------
Patching code references sysinv.openstack.common.policy

A method that was being referenced had its method renamed by
https://review.opendev.org/c/starlingx/config/+/849904

patching code needs to be updated to the new method signature otherwise zuul(pylint) as well as any
patching code that exercises that code-path will fail.

Severity
--------
Major

Steps to Reproduce
------------------
Zuul will fail pylint

Expected Behavior
------------------
Patching code submissions that used to pass zuul, should still pass zuul

Actual Behavior
----------------
Zuul fails due to the code change from that external sysinv code change

Reproducibility
---------------
Its a method renaming issue.
It will block all patching code changes from passing zuul until patching code adapts to the new method signature.
It would also impact patching calls that invoke the 'enforce' method.

System Configuration
--------------------
N/A

This issue affects more than just zuul.
