This is an automated cherry-pick of #18439
What is changed and how it works?
Issue Number: Close #18463
What's Changed:
In previous work #17801, TiKV has introduced the detection mechanism for kvdb disk to detect I/O hang issues.
However, recent customer feedback highlighted the need to extend detection coverage to I/O jitters, ensuring TiKV can automatically recover from abnormal states caused by KVDB I/O jitters.
Therefore, this ticket is built to tracks the development efforts to enhance TiKV’s I/O jitter detection and recovery mechanism. And the majority parts of this change are listed as followings show:
raftstore.inspect_kvdb_interval: 2s -> 100msSlowScore::ratio_thresh：60% -> 10%Related changes
