- Introduced a function to determine cache TTL based on setting keys, allowing critical settings to have shorter cache durations. - Updated cache logic in Create, Update, Get, and GetValueByKey methods to utilize the new TTL management, improving performance and consistency in settings retrieval.

先 draft 了 2.0.18 大改动已经很多了， 暂时不合这个，等合进 2.0.19。 |
- Removed the dynamic TTL function and standardized the cache TTL to a fixed duration for all settings. - Updated cache logic in Create, Update, Get, and GetValueByKey methods to use the new fixed TTL, enhancing code clarity and maintainability. - Added a new function to restart the core service after resetting settings, improving the reset command's functionality.

What this PR does / why we need it?
中间件需要多次读取 sqlite 里的数据，在 io 差的服务器可能会造成一定负担
Summary of your change
给中间件所需参数缓存进 go-cache内存(五分钟缓存，更新会刷新缓存），减少数据库 io 调用
