> continued from CASSANDRA-483: an autobootstrapped node will pick the most-loaded node
to get a token from.  but if we autobootstrap multiple nodes, we don't want all of them picking
tokens right next to each other in the same ring segment.  additional bootstrapping nodes
need to take this into consideration, ideally without needing an error-prone "rollback" of
load guessing if one of the bootstraps fails.
