feature_interaction_constraint like xgboost

[marquisthunder]

Dear YDF team,
As it is possible to specify feature interaction constraint[1] in xgboost to use domain knowledge to improve the model, is it possible to add this feature in ydf? It would be great when combined with oblique split as sometimes the oblique split condition is difficult to use in model explanation.
