What happened

1、新版分重构的不干净。
0.5.8版本中以及main分支中(截止该issue提出时刻)。
dbgpt/app/knowlege/service.py中第223行，调用了未被定义的方法_sync_knowledge_document。

2、chroma库标量过滤，需要给的入参格式是 {"$and": [{"field_a":1, "filed_b": 2}]}，我们代码dbgpt/storage/vector_store/chroma_store.py 第198行的实现需要调整一下

现在的逻辑解析出来的格式是{"$FilterCondition.AND": [{"field_a":1, "filed_b": 2}]}
3、chroma向量库召回数据的score计算，重构前langchain的实现如下图，代码位置langchain/schema/vectorstore.py253行

重构后丢失了评分的计算，重构后的代码位置dbgpt/storage/vector_store/chroma_store.py 第136行

4、document的mysql表操作没有及时close链接，导致当并发高时，会出现链接不可用
代码位置dbgpt/app/knowledge/document_db.py第221行和第255行
