Added load balancer exception class
Replaced NotSupportedException with new ConDepLoadBalancerException. Fixed issue where load balancer was taken online after failure during offline and/or rare execution failures.
Implemented a loop of devices where an attempt is made to retreive real server from the first deviceid and if failed tries the next. Don't really know ACE well enough to know if this is the way to do it, but there's no info on the device object to tell which device is active.
