> This is a utility class which will be part of the FailoverController. The
> class starts a daemon thread which periodically monitors an HAService,
> calling its monitorHealth function. It then generates callbacks into another
> class when the health status changes (eg the RPC fails or the service returns
> a HealthCheckFailedException)
