aaf35ee49cBackport #27000 by @wxiaoguang This PR reduces the complexity of the system setting system. It only needs one line to introduce a new option, and the option can be used anywhere out-of-box. It is still high-performant (and more performant) because the config values are cached in the config system.  Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
