> When Primary Node changes, all components (Processors, Controller Services,
> Reporting Tasks) have the ability to be notified via the
> {{@OnPrimaryNodeChanged}} annotation. This is done in the FlowController from
> the LeaderElection thread.
> However, if a component blocks indefinitely, that thread is blocked, and
> there's no way to terminate it.
> This should instead be done in a background thread.
