Refactor `/apiAuth/cors.feature` tests for OCIS

[SwikritiT]

The tests in apiAuth/cors.feature needs to be refactored so that they run in OCIS too. right now we have step And user "Alice" has added "https://aphno.badal" to the list of personal CORS domains which runs some occ comands which is not relevant in OCIS. So the tests there need some kind of refactoring so that they support both backends.

https://github.com/owncloud/core/blob/1252e5ddab6532c3d77d870e133fee4cafc74c70/tests/acceptance/features/apiAuth/cors.feature#L8-L49

the tests in this file are currently in expected to fail https://github.com/owncloud/ocis/blob/66f2cf35624de7171f1b7b6362e573ca2b9f6e60/tests/acceptance/expected-failures-API-on-OCIS-storage.md?plain=1#L1128

Right now if I run tests from this file on OCIS it fails as so

Feature: CORS headers

  Background:                                                                              # /home/swikriti/www/core/tests/acceptance/features/apiAuth/cors.feature:4
    Given user "Alice" has been created with default attributes and without skeleton files # FeatureContext::userHasBeenCreatedWithDefaultAttributesAndWithoutSkeletonFiles()

  Scenario Outline: CORS headers should be returned when setting CORS domain sending Origin header # /home/swikriti/www/core/tests/acceptance/features/apiAuth/cors.feature:8
    Given using OCS API version "<ocs_api_version>"                                                # FeatureContext::usingOcsApiVersion()
    And user "Alice" has added "https://aphno.badal" to the list of personal CORS domains          # CorsContext::addDomainToPrivateCORSLists()
    When user "Alice" sends HTTP method "GET" to OCS API endpoint "<endpoint>" with headers        # OCSContext::userSendsToOcsApiEndpointWithHeaders()
      | header | value               |
      | Origin | https://aphno.badal |
    Then the OCS status code should be "<ocs-code>"                                                # OCSContext::theOCSStatusCodeShouldBe()
    And the HTTP status code should be "<http-code>"                                               # FeatureContext::thenTheHTTPStatusCodeShouldBe()
    And the following headers should be set                                                        # FeatureContext::theFollowingHeadersShouldBeSet()
