In order to support graceful deletion, the resource object will need access to the TTL value in etcd. Also, in the future we may want to get the creation index (distinct from modifiedindex) and expose it to clients. Change EtcdResourceVersioner to be more type specific (objects vs lists) and provide a default implementation that relies on the internal API convention. Also, rename etcd_tools.go to etcd_helper.go and split a few things up.
