When a CredentialIssuer is switched from one service type to another (or switched to disabled mode), the `impersonatorconfig` controller will delete the previous Service, if any. Normally one Concierge pod will succeed to delete this initially and any other pods will see a NotFound error.
Before this change, the NotFound would bubble up and cause the strategy to enter a ErrorDuringSetup status until the next reconcile loop. We now handle this case without reporting an error.
