FEAT: Astra DB Source Connector Support

[erichare]

This Pull Request adds support for Astra DB as a source connector. The idea being that some collections in Astra DB may not be vector collections. Here, we can pull structured data, and use the destination connector to produce a structured table with vector support. CC @potter-potter

Hi @potter-potter , just wondering would it be helpful to you if i merged in the changes from https://github.com/Unstructured-IO/unstructured/pull/3179 into this PR? I can do so and close the other PR if so!

@erichare This looks like it's pretty close to being done.

EDIT: Also just wanted to check if you want me to just merge in the changes from https://github.com/Unstructured-IO/unstructured/pull/3179 into this one, and close 3179? just let me know.

Thanks @potter-potter ! I've done that, made the update to the output paths, and did some little cleanup of the imports. Let me know if this looks good or if there's anything else to address. Thanks so much for the reviews.
