for details.
> LinearRegressionSummary will store stats from training, such as objective value on each
iteration, avg residual, etc.  It will store a LinearRegressionResults instance for the results
on the training dataset.
> The assignee should make sure to coordinate with others working on [SPARK-7674].
> Note: This can add a limited number of metrics.  We can always add more in the future.
