      Description

      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)
