`CsvTableSource` is inheriting both `StreamTableSource` and
`BatchTableSource` so they should be traits.
I don't think that adding a method that only calling implementation from a
trait is a big issue. In any case we do not duplicate the code and do not
re-implement methods.
Do you have any concerns about this?
