Is your feature request related to a problem? Please describe.
Currently, it is possible to stream RecordBatches using RowIterator._to_arrow_iterable and this is done internally in the to_arrow method. There is a public to_dataframe_iterable method and so it feels like there should be a matching to_arrow_iterable method for the same reasons the Pandas version exists.

Describe the solution you'd like
Promote _to_arrow_iterable to to_arrow_iterable
