NIFI-745: Only call methods with @OnDisabled once, regardless of whether or not
they succeed
> Disabling Controller Service stuck
> ----------------------------------

>
> Per the nifi-api a controller service OnDisable method will be invoked when
> the user disables that service. If that method fails with an exception it
> will be retried a short time later. This will continue until it successfully
> completes.
> Unfortunately, this means that if services continually throws an exception
> during OnDisable the user will not be able to do anything with the service.
> This is because controller services need to be Disabled in order to support
> editing its configuration or attempting to Enable. The service in question
> will not transition to the Disabled state until its OnDisable completes
> without issue.
