Description

Currently, multiple nodes can join the ring with the same token (particularly when people copy the data directory between machines). The symptom is that the new endpoint joins the ring successfully, but both nodes can only see themselves in the ring (according to nodetool).

Instead of this behaviour, we would want gossip to die rather than joining with a duped token.
