### Description
Saw the following error when fetching task status from S3. This is due to S3
rate limiting on query, we should retry the operation in this case.
```
com.amazonaws.services.s3.model.AmazonS3Exception: Slow Down (Service:
Amazon S3; Status Code: 503; Error Code: 503 Slow Down; Request ID:; S3
Extended Request ID: ; Proxy: null)

```
Now change to use `S3Utils.retryS3Operation` for task log fetch, same as
task file push method.
#### Release note
