.Net: Python: Support listing all keys on vector store

[alliscode]

The original issue was filed for dotnet but we should make sure python supports this as well. See #9892

Hi, I’d like to work on the _inner_get_all_keys feature. My plan is to implement a method that retrieves all keys from the collections of different backends: PostgreSQL, Redis, Weaviate, In-memory, Azure Cosmos DB, and Azure AI Search.
Is this something I can work on, or is it already being addressed?

I’d appreciate any feedback or suggestions you may have.

Thanks!
Kirity

@Kirity12 thanks for the offer, we first need to decide how we will approach that across both dotnet and python and where the generic method lives, vs the implementations, I've created a ADR for that here #9932 , once that is decided, we can do this work, I'll keep you posted!

@eavanvalkenburg Thank you for the update! I'll keep an eye on the ADR for the approach across Python. Kindly let me know, once the decision is made. Looking forward to working on it!
