fix: Fix clustering compaction task leak (#36800) 
issue: #36686 

bug reason:
- The clustering compaction tasks on the datanode were never cleaned up.
- The clustering compaction task contains a mapping from clustering key
to buffer, this caused a large memory leak.

fix:
- clean the tasks on datanode by datacoord when clustering compaction
finished.
- reset the mapping that from clustering key to buffer on datanode when
clustering finished.

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.
