I need to import some Q&A text，not need LLM to generate results。I add code to support uploading qa files。 Q&A text format:

Q1: 只剩一个心脏了还能活吗？
A1: 能，人本来就只有一个心脏。

Q2: 爸爸再婚，我是不是就有了个新娘？
A2: 不是的，你有了一个继母。"新娘"是指新婚的女方，而你爸爸再婚，他的新婚妻子对你来说是继母。

Q3: 樟脑丸是我吃过最难吃的硬糖有奇怪的味道怎么还有人买
A3: 樟脑丸并不是硬糖，而是一种常见的驱虫药，不能食用。虽然它的味道可能不太好，但是由于其有效的驱虫效果，所以仍然有很多人会购买。

No need to go through llm, just go through a vectorized model

@jiandanfeng Yes, but there are people who won't use it or find it troublesome. We want to be able to upload QA files directly.

Looking forward to great solution. This feature is indeed very necessary because according to the provided QA file, users can directly match Q-Q when asking questions, which is very beneficial for T2S scenarios. Based on similar questions, the corresponding SQL can be accurately matched。
