#2102

Description (What does it do?)

This PR removes EDX_API_KEY usage as Open edX is going to remove the EDX_API_KEY. Details can be found at openedx/edx-platform#34039. It also fixes a potential impact on the deactivate_enrollment API for non-staff users if the EdX-Api-Key is removed.

Screenshots (if appropriate):

• Desktop screenshots
• Mobile width screenshots

How can this be tested?

• Fetch, check out to this branch, install edx-api-client with editable mode having this branch, and make sure edx is configured.
• Test all the endpoints that currently utilize EdX-Api-Key for client requests. For example.
  • You can check the following tasks if they are working with open edX without issue.
  • openedx.tasks.change_edx_user_email_async
  • openedx.tasks.change_edx_user_name_async
  • openedx.tasks.create_edx_user_from_id
  • openedx.tasks.create_user_from_id
  • openedx.tasks.regenerate_openedx_auth_tokens
  • openedx.tasks.repair_faulty_openedx_users
  • openedx.tasks.retry_failed_edx_enrollments
  • openedx.tasks.update_edx_user_profile
  • courses.tasks.subscribe_edx_course_emails
  • courses.tasks.sync_courseruns_data
    You can also use management commands to test where applicable. i.e:
  • regenerate_edx_auth_tokens
  • repair_missing_courseware_records
  • retry_edx_enrollment
  • sync_enrollments
  • update_edx_profiles

Important to be tested:

• Test user enrollment with different course "privileged" modes, i.e., audit, and verified.
  • This is how I tested, But It would be good if the tester tests the different enrollment through front-end.

from edx_api.client import EdxApi
api = EdxApi({"access_token": "<ACCESS_TOKEN>"}, base_url="http://host.docker.internal:18000")
api.enrollments.create_student_enrollment(course_id="course-v1:edX+DemoX+Demo_Course", username="verified", mode="audit")

• Test the deactivate_enrollment API, here are the few mitxonline features/management commands I found that directly or indirectly use this API.
  • unenroll_enrollment
  • refund_fulfilled_order
  • transfer_enrollment
    or can test the course unenroll from user dashboard.

@asadali145 can you please review as discussed to bump edx-api-client version to 1.9.0? The edx-api-client version 1.9.0 was published at mitodl/edx-api-client#105.

LGTM!

There is an issue with the enrollments which is not part of this PR. I will try to finalize the steps and create another issue.

@asadali145 / @mudassir-hafeez Thanks. It would be good to keep MITx Online dev team in loop about this change.
