Is this log needed here? If it is needed not sure if it should be undefined cluster

Ops, thank you for catching it. I just forgot to delete this line - fixed!

I think this behaviour is different from the delete policy of the other hook types, as far as I remember in gitops-engine the delete policy would be compared with the whole app status instead of just the hook status. We might want to keep the behaviour same or else it can be confusing. I understand at deletion we probably won't have the app status to compare maybe so might be better to have special deletion policy just for the delete hooks?

Another question here, what do we do if the deletion policy condition isn't met. Does the app itself remains or is it just the hook that sticks around?

You are right. App deletion does not have status, however, I think the use case is similar: the user just needs control to preserve some hook for debugging. To match with gitops engine behavior it makes sense to use aggregated hooks status. Implemented

If the deletion policy does not match, then the hook stays. It matches Helm behavior . Updated documentation as well. Thank you for review @gdsoumya . PTAL |

Closes #7575
PR introduces Post delete hooks support. Hooks are executed during application deletion after all resources as removed. Hooks respect deletion policies.
