fix: skip the sync peer that does not belong to the scheduler cluster

[gaius-qi]

Description

This pull request includes changes to the manager/job/sync_peers.go file to improve the synchronization of peers, specifically addressing compatibility with the Rust client. The most important changes include updating the SyncPeers interface documentation and adding a condition to handle scheduler clusters in the mergePeers function.

Documentation update:

• manager/job/sync_peers.go: Updated the SyncPeers interface comment to specify that it is only supported in the Rust client.

Functionality improvement:

• manager/job/sync_peers.go: Added a condition in the mergePeers function to skip sync peers that do not belong to the scheduler cluster, as the Golang client lacks the SchedulerClusterID field.
