"snapshot" Restore/Status code was the only remaining dependency of client on 'server' code. The code is solelly used by etcdctl. Long-term the snapshot code should be migrated to 'etcdadm' style of tool such that we can distinguish tool solelly depending on networking API vs. tools that operation on etcd files directly. We left snapshot.Save() code in clientv3.snapshot package, such that clients can benefits from automated download&safe to file snapshot functionality over the wire.
