LavinMQ::Shovel::MultiDestination

A shovel's list of dest-uris, used one at a time: every start draws one at random and all deliveries of that run go to it. There is no failover. The chosen destination reports its outcomes straight to the Runner, so an Abort counts towards the shovel's abort threshold as it would with a single destination. If the chosen destination cannot start, start raises and the Runner reconnects with backoff; that next start draws again, as does every start after a pause or a reconnect.
