Implement vector upsert manually - Update File For Vector Datasource

Because there is no corresponding vector node that can implement the update operation for the uploaded file, I manually implemented the query, deletion and insertion operations of qdrant vector, I think this process should be able to be borrowed from other vector databases.

Features:

  1. The operations of query, deletion and upload of qdrant were manually implemented using HTP node
  2. It also meets the parsing requirements of text documents, md documents, pdf documents and csv documents
  3. The upload process also includes splitting the file content into a chunk list by a fixed size, and then calling each chunk respectively
  4. The embeding interface generates vector data and finally formats it into the json structure of insert
  5. Double-layer Loop: inside and outside
