[SW-1768] Get Default Values of AutoML Parameters Synchronized with H2O-3

[mn-mikke]

I was also thinking about referencing H2O-3 default values directly to have them specified only once. But since they must be specified also in Python API, I just changed values on the SW site.

Thank you @mn-mikke. Just question -> what does it mean for the user that maxRuntimeSecs has changed to 0 by default? Does it mean take as much time as you need?

[mn-mikke]

@jakubhava According what I remember from the discussion with @seb-h2o, it's exactly as you described. maxModels -> 0 also means an unlimited number of models. I will add note to a migration guide

@seb-h2o please correct me if I'm wrong.

Thanks for explanation!

to clarify:

• maxRuntimeSecs = 0 means unlimited time.
• maxModels = 0 means unlimited amount of models.
• if both are set to 0, backend will automatically change the default for maxRuntimeSecs to 1h.
• if both are set to value != 0, both are applied and the first limit reached will prevail.
