> default behavior should be to remember the nodes we've seen before.  we're already storing
ip/token pairs in systemtable, but we're not removing them when removetoken is issued.
> we probably want to leave some trace of nodes-that-used-to-participate-but-were-removed,
but instead of having a historical track in systemtable let's just add something to the gossip
listener in StorageService that logs token when a node comes up.
> finally, there should be a flag (-D?  config?) for bringing up a node in don't-assume-anything-about-the-ring
mode as a fallback in case we run into more funky token-related bugs.
