Walkthrough
The recent updates introduce a new configuration parameter, admin-thread-pool-size, and improve the PikaConf and PikaServer classes to handle admin commands separately via a distinct thread pool. Additionally, several command-related adjustments enhance management and monitoring capability, including the introduction of flag kCmdFlagsMonitor and additional checks for admin commands. These changes collectively aim to optimize the handling of admin requests efficiently in the system.

将pika的info ping 等admin命令拆分出主线程，用单独的线程池去处理
为了避免 config 配置过多 这里考虑用unorderd_set写死 可以通过config修改 https://github.com/OpenAtomFoundation/pika/issues/2399
