CORS not enabled despite correct configuration

[Joshua Cornutt]

I've submitted a patch here: https://review.opendev.org/c/openstack/manila/+/907012

Description
===========

The [cors] configuration section is completely ignored and CORS is left disabled.

Steps to reproduce
==================

* Set the [cors] section in the configuration file
* start the API service, and attempt to connect from an external frontend application

The config used is below and is what works on all other OpenStack services.

[cors]
allowed_origin = *

Expected result
===============

CORS is enabled and responds with the appropriate headers.

Actual result
=============

CORS is not enabled and external frontend applications fail to connect.

Environment
===========

kolla-ansible deployed 2023.2 and master.

OK I thought this issue is very specific to standalone manila-api but in fact it also affects the wsgi app.

[Takashi Kajinami (kajinamit)]

The problem is that set_lib_defaults is not called. this means that even the default policy file override is not applied...

EDIT: Ignore this. Seems we have a different set_override which is taking effect.

    Fixing skipped default override for CORS options

    Some of the cores middleware options should have overridden default
    values but the override method was not actually called so the library
    defaults are still used.
