Do not lookup the service instance when finalizing an UPSI binding

[danail-branekov]

Bacground

Currently we have a main-delegates architecture of the binding controller. The main controller looks up the binding instance and provides it to the appropriate delegate controller.

In the case of UPSI bindings, the delegate controller does not need the service instance when finalizing the binding. It makes no sense finalization to fail if the service instance cannot be looked up

Action to take

Refactor the delegate controllers to

• Not receinve the instance in their finalize method
• The managed service binding controller should lookup the service instance itself
