### What problem does this PR solve? 1. What problem was fixed (it's best to include specific error reporting information). How it was fixed. Scanner metrics added by https://github.com/apache/doris/pull/40496 can not distinguish different workload group. This pr added metrics for all `SimplifiedScanScheduler`, and we can see metrics like this: <img width="1889" alt="image" src="https://github.com/user-attachments/assets/796a6b18-2286-4f59-813f-3cbc68b9b06b";> 2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be. Some metrics added by https://github.com/apache/doris/pull/40496 is removed. They are replaced by new metrics. 3. What features were added. Why this function was added. Metrics used to monitor scanner block queue like `scan_operator_get_block_from_queue` is added. We need them to find abnormal behavior of scanner. <!-- If this PR is followup a previous PR, for example, fix the bug that introduced by a related PR, link the PR here --> Related PR: https://github.com/apache/doris/pull/40496 Overall view: <img width="1885" alt="image" src="https://github.com/user-attachments/assets/f904f810-a009-4050-a18d-04233d18f9b7";> ### Check List (For Committer) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
