Moved some code from Ivory to list/read/write/delete files from locations

I created a `LocationIO` object having the necessary configurations to do IO operations, extracted from the `IvoryLocation` object in Ivory.
Should be able to refer to this for `tempUniquePath`

And this for the s3 bucket and path
