      cluster type 1, content hashing

      Description

      when we enable full clustering, the performance is unacceptable, it add about 24ms per request. we'd expect <10ms latency for each cluster request.

        This patch will reduce the cluster response time. In my test, cluster memory cache hit:
        300qps(9.9ms~10.2ms); 600qps(10.5ms~12ms). I did not test the rt under very high pressure.

        Base on the current framework, it`s hard to reduce the cluster rt to smaller than 10ms. I will continue to focus on performance issues。
