QuantileDMatrix with xgboost.DataIter and enable_categorical

[ljw20180420]

When use QuantileDMatrix with xgboost.DataIter, feature_types cannot be used, but enable_categorical can be used. Does that mean all integer features are treated as categorical?

feature_types could be passed using the next() method similar to other meta data.
