Title: add resubmit method to BatchList

Resubmit automatically create new batches to get the next set of results from DynamoDB.

The new request is infered from the ``UnprocessedKeys`` field of the answer.

If this field was empty, ``None`` is returned instead of the result set. I choosed ``None`` over letting ``DynamoDBValidationError`` normal behavior propagate because the request is supposed clean at this point and it allows the use of a clean loop
