[Feature-Request]Parameter to set features selected absolutely

[lamrongol]

You can make specified features more selectable by feature_weights

XGBoost allows you to assign different selection probabilities to features when using the colsample_bytree or colsample_bylevel parameters.

However, this just increase the probabilities, doesn't guarantee selected absolutely.

This can be useful when you know certain features are more informative than others and want the model to focus on them.

If "certain features are more informative than others", selected absolutely is more preferable, isn't it?
