Provide a Predict CLI command, similar to the mlnet-autotrain command

Greetings @inchiosa -- I fully agree, this has been a rather long standing issue. We provide a way to automatically train a model from the commandline, but we do not provide a way to score a test dataset from the commandline.

I think it would look like:

mlnet predict --test-dataset TestData.tsv --model file.zip 

This would do a bulk prediction of all rows in the test dataset.

One difficulty is knowing the input schema. For this I would recommend that the mlnet auto-train stores the text-loader settings in the model zip file.

I'm very surprised to find this isn't already a feature
