### Motivation When deploying Bookie on K8s with limited CPU resources, once the CPU is throttled, the journal write latency will increase. One case of causing CPU throttle is garbage collection triggered.  <img width="1711" alt="image" src="https://github.com/apache/bookkeeper/assets/5436568/26bdd6d8-a52d-4e42-a157-9cac3684e9f7"> The journal write latency is sensitive with the journal CPU, especially when the CPU is throttled. ### Modifications Increase the JournalThread and ForceWriteThread priority to reduce the latency impaction when the CPU is being throttled. -- This is an automated message from the Apache Git Service.
