Remarks
Whenever SanteDB sends messages to another system using messaging, there is no guarantee that the remote endpoint will be available,
or accessable, etc. Therefore all messages which are sent (dispatched) to a remote system are first queued using this wrapper service.
The purpose of the dispatcher queue is the store the outbound message locally in some persistent place, then to notify any listeners that a new message is ready for sending. If the message cannot be sent, then the sending service should place the message back onto the queue or onto a dedicated deadletter queue.
