fix: Update segment compactTo when compactTo segment is compacted (#28755) 
Related to #28736 #28748
See also #27675
Previous PR: #28646

This PR fixes `SegmentNotFound` issue when compaction happens multiple
times and the buffer of first generation segment is sync due to stale
policy

Now the `CompactSegments` API of metacache shall update the compactTo
field of segmentInfo if the compactTo segment is also compacted to keep
the bloodline clean

Also, add the `CompactedSegment` SyncPolicy to sync the compacted
segment asap to keep metacache clean

Now the `SyncPolicy` is an interface instead of a function type so that
when it selects some segments to sync, we colud log the reason and
target segment

Data Node

DataNode is the component to write insert and delete messages into persistent blob storage, for example MinIO or S3.

Dependency

  • KV store: a kv store that persists messages into blob storage.
  • Message stream: receive messages and publish imformation
  • Root Coordinator: get the latest unique IDs.
  • Data Coordinator: get the flush information and which message stream to subscribe.
