Add interaction_constraints support to GBM + documentation issue

Description

It would be useful if GBM supported interaction_constraints like xgboost does.

The current documentation shows an example usage with GBM, but it does not work because it is only supported by xgboost: http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/algo-params/interaction_constraints.html

I think it would also be nice if there was a way to specify interactions that are disallowed, instead of specifying all those that are allowed.
