Cover ClusterClass provisioning in E2E #1354
Description
/kind feature
Describe the solution you'd like
As a developer I'd like to have ClusterClass provisioning covered in E2E tests.
Anything else you would like to add:
This is a follow up of #1351 (comment). There are templates for creating ClusterClass and Cluster from topology but this case needs to be added to the list of scenarios covered in E2E.
