vector store: qdrant: Add the metadata (payloads) to the vector store and implement search/filter

[navinsubramani]

1. Currently metadata is not added to the vector store, as it supports the dictionary and we might need to convert the labview key-value pairs to the dictionary.
2. Once the dynamic key-value pair (metadata) is added to the vector store, implement the hybrid search (filters), etc. the capabilities are already provided under the qdrant.
3. Improve the error handling with the HTTP calls (review each method in qdrant class and improve the error handling, and performance)
