Run e2e tests against ocis with keycloak as idp

[saw-jan]

Follow up of #9518

Reasons:

• during the release process we run e2e tests on different instances, except only keycloak.
• the idea of running e2e on a k8s cluster, where we have an instance as similar to production as possible, where we track metrics and where k6 tests are already running

what e2e test should have (using keycloak admin console api):

• [ ] add users to group ([ocis] [FR] Import also groups from Keycloak ocis#5538)
• [ ] delete users from group ([ocis] [FR] Import also groups from Keycloak ocis#5538)
• change user role ([tests-only][full-ci]assign role to user through keycloak #10119)
• skip features: https://github.com/owncloud/web/tree/master/tests/e2e/cucumber/features/smoke/admin-settings/users.ocis.feature https://github.com/owncloud/web/tree/master/tests/e2e/cucumber/features/smoke/admin-settings/groups.ocis.feature

The groups created in oCIS are not accessed in the keycloak and vice versa. So, the addition of user to group and deletion of users from the group is not possible.

addition of user to group is possible on keycloak admin panel

hmm but sharing to group (created in keycloak is not possible). maybe it's bug

yes, create a group and add a user to the group through keycloak is possible but this created group information is not available in oCIS.

I talked to @rhafer. It's not bug, it is feature request. Thanks for creating report

[rhafer]

Here's the existing feature request owncloud/ocis#5538

[saw-jan]

Since group provisioning via Keycloak is not available yet we can work on e2e regarding groups after the feature has been implement.
For now, we will mark this ticket as done.
