Scaling: optimize the clearing peer mechanism to mitigate the impacts to tail latency. #18107
Description
Development Task
This task is a sub-task of #18042, which is used to mitigate the latency impacts during scaling operations.
It mainly consists of two parts:
- Do not use ingest operations when clearing stale ranges during the balancing regions process.
- Do not clear data of offline stores during the scale-in process, as this data will be automatically cleared when the corresponding node goes offline.
