      Description

      MQTT clients that create durable subscriptions and that operate in a network of Brokers can receive duplicate messages when they start failing back and forth between brokers in the network.

      We should investigate using Virtual Destinations under the covers instead of durable topics subscriptions as this is a known problem with the durable topic case. With Virtual Destinations the client would be subscribed to a Queue that would receive all messages sent to the target Topic.
