feat: authorize advanced settings endpoints via openedx-authz when fl…

[wgu-taylor-payne]

Description

Add the option to authorize with openedx-authz for the advanced settings related endpoints. If the AUTHZ_COURSE_AUTHORING_FLAG is enabled for the course, then the system will do the permission check against openedx-authz.

This functionality depends on features introduced to openedx-authz in version 0.21.0.

Supporting information

Resolves #37926.

Testing instructions

To run the relevant automated tests:

pytest --ds=cms.envs.tutor.test \
"cms/djangoapps/contentstore/rest_api/v0/tests/test_advanced_settings.py::AdvancedSettingsAuthzTest" \
"cms/djangoapps/contentstore/rest_api/v1/views/tests/test_proctoring.py::CourseProctoringErrorsViewTest"

To manually test:

1. Ensure that the new policy is loaded by running ./manage.py cms load_policies
2. Ensure that the AUTHZ_COURSE_AUTHORING_FLAG flag is enabled for the given course (see feat: Add Waffle flag for AuthZ for Course Authoring #37985).
3. If staff or admin, you should be able to access the advanced settings page for any course (e.g. http://apps.local.openedx.io:2001/authoring/course/course-v1:OpenedX+DemoX+DemoCourse/settings/advanced)
4. If not staff or admin, then you will have to assign the COURSE_STAFF role to the user with the scope being the course you are testing access for. Afterwards the user should have access to the advanced settings page.
