Proposed changes

Issue Number: close #xxx

Problem summary

If this replica is cooldown replica, MUST generate a new cooldown_meta_id to avoid use cooldown_meta_id generated in old cooldown term which may lead to such situation:
Replica A is cooldown replica, cooldown_meta_id=2,
Replica B: cooldown_replica=A, cooldown_meta_id=1
Replica A: full clone Replica B, cooldown_meta_id=1, but remote cooldown_meta is still with cooldown_meta_id=2
After tablet report. FE finds all replicas' cooldowned data is consistent(cooldown_meta_id=1)
Replica A: confirm_unused_remote_files, delete some cooldowned data of cooldown_meta_id=2
Replica B: follow_cooldown_data, cooldown_meta_id=2, data lost

Checklist(Required)

  • Does it affect the original behavior
