Access paylod from Qdrant

[dsporcaro]

I'd love to be able to access some of the metadata fields through qdrant directly through the RM Client on DSPy. Here's the Qdrant documentation on this: https://qdrant.tech/documentation/concepts/search/#payload-and-vector-in-the-result

The motivation is I have metadata on the parent of the chunks, including the title of the document and its source-URL. I'd love to fetch that as part of the retrieval and make it available in my code. This doesn't seem possible with the current qdrant client.
