Pub/Sub topic where replay is requirederror

pubsub-replay-required

The design declares that consumers must be able to replay history. A fan-out topic that does not retain messages cannot deliver that.

— all of these hold:
— the design requirement `messaging.replay` is true
— the node's `replay` is false
