[Sheepdog] [PATCH] sheep: remove useless log in membership change path

[zituan at taobao.com]

From: Yibin Shen <zituan at taobao.com>

when large set of nodes join sheep cluster, for example:
a cluster with 1000 new nodes joining, nearly 100MB log will
be generated in each node. these logs are almost useless.
