This class store the cache value per thread. If a service,method,consumer or provided is configured with key cache with value threadlocal, dubbo initialize the instance of this class using ThreadLocalCacheFactory to store method's returns value to server from store without making method call.

      e.g. <dubbo:service cache="threadlocal" />
