issue: #42176 pr: #42177 Remove the mutual exclusion constraints between channel and segment balance tasks to allow them to run concurrently. Changes include: - Remove permitBalanceChannel() and permitBalanceSegment() methods from RoundRobinBalancer - Update ChannelLevelScoreBalancer, MultiTargetBalancer, RowCountBasedBalancer, and ScoreBasedBalancer to remove constraint checks - Allow segment balance tasks to proceed even when channel balance tasks are running - Update test cases to reflect new behavior where balance tasks no longer block each other - Improve error handling in task executor by preferring serviceable shard leaders for segment release operations - Add fallback logic to find latest shard leader when serviceable leader is not available This change improves the efficiency of load balancing by removing unnecessary coordination overhead between different types of balance operations.
