         e.g. 1) <dubbo:service cache="lfu" cache.size="5000" cache.evictionFactor="0.3"/>
          2) <dubbo:consumer cache="lfu" />
 
     LfuCache uses url's cache.size value for its max store size, url's cache.evictionFactor value for its eviction factor,
 default store size value will be 1000, default eviction factor will be 0.3
