> People often encounter a schema disagreement where just one node is out of sync.  To
get it back in sync, they shutdown the node, move the Schema* and Migration* files out of
the system ks, and then start it back up.  Rather than go through this process, it would be
nice if you could just tell the node to reset its schema.
