#### redis缓存组件，特性如下：

1. 统一缓存调用入口：ICache，支持内存缓存（开发模式）和分布式缓存（生成模式）自由切换；
2. 兼容codis；
3. 使用分布式缓存时支持二级缓存（闪存）。

#### 调用如下：

##### 初始化：

    var services = new ServiceCollection();
    services.AddMemoryCache(option => { });
    services.AddSingleton(sp => new RedisService("localhost:32768"));
    services.AddDistributedRedisCache(option => { option.InstanceName = "local"; });
    services.AddSingleton<ICacheSerializer, JsonCacheSerializer>();
    services.AddSingleton<ICacheProvider, DistributedCacheProvider>();
    services.AddSingleton<CacheFactory>();

##### 调用代码：

    class PostManager
    {
        private readonly ICache m_Cache;
    
        public PostManager(CacheFactory cacheFactory)
        {
            m_Cache = cacheFactory.GetCache("Post");
        }

        public Post Get(int id)
        {
            var key = CacheKey.NewCacheKeyString(id);//最终格式：local:Post:{id}
            var data = m_Cache.Get<Post>(key);
            if(data == null){
                //TODO: get from database
                //m_Cache.Set(key, data);
            }
            return data;
        }
    
        public void Delete(int id)
        {
            var key = CacheKey.NewCacheKeyString(id);
            //TODO: delete from database
            m_Cache.Remove(key);
        }
    }
