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.
