------------------------------------------------------------------
The naive solution of just using the IP->token mapping we already persist
trades this problem for a new one: it would become difficult to change the IP
of an existing node. Granted, this is a rare operation -- but so is shutting
down the entire cluster.
One way to address this is using UUIDs for identity (rather than IP, directly)
and mapping UUID -> token, UUID -> IP separately.
