fix: Fix exclude nodes clearing logic position in load balancer retry (#42577)
issue: #42561
Move the exclude nodes clearing logic from ExecuteWithRetry to
selectNode after shard leader cache refresh to ensure proper retry
behavior:
- Remove premature exclude clearing in ExecuteWithRetry that happened
before shard leader cache update
- Add exclude clearing logic in selectNode after refreshing shard leader
cache when all replicas are excluded
- Ensure multiple retries can properly update shard leader cache and
clear exclude list when needed
- Add comprehensive tests for edge cases including empty shard leaders
and mixed serviceable node scenarios
