Stefano Lottini	4f4b020582	Add "Astra DB" vector store integration (#12966 ) # Astra DB Vector store integration - Description: This PR adds a `VectorStore` implementation for DataStax Astra DB using its HTTP API - Issue: (no related issue) - Dependencies: A new required dependency is `astrapy` (`>=0.5.3`) which was added to pyptoject.toml, optional, as per guidelines - Tag maintainer: I recently mentioned to @baskaryan this integration was coming - Twitter handle: `@rsprrs` if you want to mention me This PR introduces the `AstraDB` vector store class, extensive integration test coverage, a reworking of the documentation which conflates Cassandra and Astra DB on a single "provider" page and a new, completely reworked vector-store example notebook (common to the Cassandra store, since parts of the flow is shared by the two APIs). I also took care in ensuring docs (and redirects therein) are behaving correctly. All style, linting, typechecks and tests pass as far as the `AstraDB` integration is concerned. I could build the documentation and check it all right (but ran into trouble with the `api_docs_build` makefile target which I could not verify: `Error: Unable to import module 'plan_and_execute.agent_executor' with error: No module named 'langchain_experimental'` was the first of many similar errors) Thank you for a review!

Stefano Lottini	a4e4b5a86f	Relax python version and remove need for explicit setup step (#12637 ) This PR addresses what seems like a unnecessary Python version restriction in the pyroject.toml specs within both Cassandra (/Astra DB) templates. With "^3.11" I got some version incompatibilities with the latest "langchain add [...]" commands, so these are now relaxed in line with the other templates I could inspect. Incidentally, in the "entomology" template, the need for an explicit "setup" step for the user to carry on has been removed, replaced by a check-and-execute-if-necessary instruction on app startup.
