This class represent a Priority Durable implementation.
Two subscribers can hold a subscription to the same durable object. One is given priority and will process events during normal operation. If, however, the subscriber with priority is disconnected and is unable to process events, the second subscriber to that durable object will take over and continue to process events as they come in. This allows failover, with backup subscribers handling events if the subscriber with priority goes down.

If set the durable object will queue multiple subscription such that the first subscriber will receive all events until it either disconnects or deletes the subscription, at which time, the next subscription request will start to receive events.
