Not having any available Istio instalation prevents deletion of Kuadrant resource

[pehala]

Suppose you do not have any Istio installation available and no OSSM 2.x present. In that case, the Kuadrant resource will have a status saying maista.io/v1 resources are missing and if you try to delete the resource, it will get stuck.

The workaround is to either fix your installation (TODO verify) or remove finalizer from a resource

I believe it is because of a missing try/catch for OSSM 2.X resource, which raises an error about missing resources.
