perf: add concurrency and pipeline for redis cache

[rfyiamcool]

summary

1. 增加 enablePipeline 配置，用户可以选配来开启 redis pipeline 模式. go-redis 库包是支持在集群模式下，pipeline 下不同key 的拆离并发操作，但这毕竟是 sdk 层实现，对于容错的处理有限，多数场景是够用了。
2. 当不开启 pipeline 模式下，以前为串行同步执行逻辑，现在为有限并发模式，内部通过索引使其返回结果有序。
3. 补全了这两个方法集的单元测试。

暂时先写 set/get 这两个方法，后面有空继续优化。😁
