- This pull request includes various changes to add a `user_agent` parameter to Azure OpenAI, Azure Search and Whisper in the Community and Partner packages. This helps in identifying the source of API requests so we can better track usage and help support the community better. I will also be adding the user_agent to the new `langchain-azure` repo as well. - No issue connected or updated dependencies. - Utilises existing tests and docs --------- Co-authored-by: Erick Friis <erick@langchain.dev>
