User Guide: Show how to re-train a model, given a set of parameters taken from a trained model

Description

Add to the Training Model section: http://docs.h2o.ai/h2o/latest-stable/h2o-docs/training-models.html

We need to finish these additions to R to make this easy (in R): I think it should already be possible in Python, but we need to add a code example here.
