---------------------------------
Seems like CASSANDRA-2928 fixes the hints issue... so we can ignore 0003 in this ticket.

> Replacing a dead node with a new one is a common operation, but "nodetool removetoken" followed by bootstrap is inefficient (re-replicating data first to the remaining nodes, then to the new one) and manually bootstrapping to a token "just less than" the old one's, followed by "nodetool removetoken" is slightly painful and prone to manual errors.
> First question: how would you expose this in our tool ecosystem? It needs to be a startup-time option to the new node, so it can't be nodetool, and messing with the config xml definitely takes the "convenience" out. A one-off -DreplaceToken=XXY argument?
