Currently, we lack visibility into the MongoDB-LangChain integration usage. This ticket aims to enhance the integration by adding wrapping library metadata. We'll achieve this by passing additional metadata to MongoClient instances during their creation. For example:

from pymongo import MongoClient
from pymongo.driver_info import DriverInfo
MongoClient(connection_string, driver=DriverInfo(name="LangChain", version="x.y.z"))
