### What changes were proposed in this pull request?
Introduce `ShuffleMetricGroup` for `numBytesIn`, `numBytesOut`, `numRecordsOut`, `numBytesInPerSecond`, `numBytesOutPerSecond`, `numRecordsOutPerSecond` metrics.
Follow up #3272.
### Why are the changes needed?
`numBytesIn`, `numBytesOut`, `numRecordsOut`, `numBytesInPerSecond`, `numBytesOutPerSecond`, `numRecordsOutPerSecond` metrics should put shuffle id into variables, which could introduce `ShuffleMetricGroup` to support. Meanwhile, #3272 would print many same logs as follows that shoud be improved:
```

```
### Does this PR introduce _any_ user-facing change?
Introduce `celeborn.client.flink.metrics.scope.shuffle` config option to define the scope format string that is applied to all metrics scoped to a shuffle:
- Variables:
- Shuffle: `<task_id>, <task_name>, <task_attempt_id>, <task_attempt_num>, <subtask_index>, <shuffle_id>`.
- Metrics:
Scope | Metrics | Description | Type
-- | -- | -- | --
Shuffle | numBytesIn | The total number of bytes this shuffle has read. | Counter |
Shuffle | numBytesOut| The total number of bytes this shuffle has written. | Counter |
Shuffle | numRecordsOut | The total number of records this shuffle has written. | Counter |
Shuffle | numBytesInPerSecond | The number of bytes this shuffle reads per second. | Meter |
Shuffle | numBytesOutPerSecond | The number of bytes this shuffle writes per second. | Meter |
Shuffle | numRecordsOutPerSecond | The number of records this shuffle writes per second. | Meter |
### How was this patch tested?
Manual test.
Closes#3296 from SteNicholas/CELEBORN-2005.
