Related to #1082
This PR is the first step to enable shuffle support in S3QS. S3QS can now support message passing between workers in different groups, as well as pipeline termination signals.
Key improvements:
Defined the message format provided by workers, enabling identification of worker IDs and partition numbers.
Since S3QS is used exclusively for shuffle tasks, it can serve as the task manager connecting the upstream and downstream of the shuffle, providing communication channels.
