Integrate with the new `object_store` crate

[matthewmturner]

I would like to be able to query data on s3 with datafusion-python and the new object_store crate. i havent had the chance to play with that crate yet but once i get the chance i would like to get the necessary functionality added here.

@matthewmturner are you planning to pick this up? If not I'm potentially interested in working on it

@wseaton go for it!
