Description

Bootstrapping nodes (including replacements) don't gossip their tokens until after they've received their schema. If the node experiences a failure before gossiping tokens, it causes the same problem CASSNDRA-15335 fixed for normal nodes - they cannot be replaced without gossiped tokens. Including tokens in the initial gossip round prevents nodes from getting into this state, although we still have to wait for the schema when the node is configured to allocate tokens for a keyspace.
