Add method to provide actual ntree value

[exalate-issue-sync]

If early stopping is enabled, GBM can reset the ntree value. Let's add a new method to get the actual ntree value (whether CV is enabled or not), rather than the original ntree value a user set before building their model.

Currently if you want the actual ntree value you need to do:

Python:
model._model_json['output']['model_summary']['number_of_trees']

R:
my_model@model$model_summary['number_of_trees']

we could add a method like:

model.ntree_actual

Sebastien Poirier commented: actually, there are currently simpler access to those properties than what is mentioned in the description.
at least for Python:
{{model.summary()['number_of_trees']}}
