TiKV graceful upgrade steps:

  1. call the pd's api pd/api/v1/schedulers with the value {"evict-leader-scheduler":storeID}, then pd will start a scheduler to evict leaders in the tikv.
  2. wait util all leaders in the tikv have be evicted
  3. call call the pd's api pd/api/v1/schedulers/{storeID} to delete the scheduler
  4. check the tikv's status until they are all available then continue to upgrade the next tikv pod
