Unable to delete ServiceInstance
Problem was found in Customer Cluster (v3.7):
Some projects where provisioned with a service from the servicecatalog. A serviceinstance was provisioned but coud not be deleted. The ServiceBinding that was referencing the ServiceInstance was prohibiting the ServiceInstance from being deleted.
Edit the ServiceBinding and remove following lines:
When the Project is already marked to be deleted, the only way to edit the ServiceBinding is through the cli.
