I was wondering if there might be a better name for this. Under the circumstances, emptyRowCount is really the best name for this parameter.

Description
CUDF cannot create a table with rows and no columns, but that is exactly what we need to be able to read some JSON input. So this adds in a new API that lets us work around this problem if we know how many rows you expect to see. This is not an ideal solutions so it not a fix for #5712 generically. But is is a stop gap, especially for cases when we know how many rows to expect.
