etcdserver

Fix wait purge file loop during shutdown.:

Previously, during shutdown etcd could accidentally remove needed wal files,
    resulting in catastrophic error 「etcdserver: open wal error: wal: file not found.」 during startup.
Now, etcd makes sure the purge file loop exits before server signals stop of the raft node.
