OpenAI Create Vector Store

Create a vector store and upload a file to it in a single operation for OpenAI's file search capabilities. This node will always create a new vector store even if one with the same name exists. Similarly, a new file will always be uploaded even if the same file has been uploaded before. If any step fails (file upload, vector store creation, or file addition), the node will stop and throw an error. The node can optionally wait for file processing to complete, which might take several minutes for large files.
