[SPARK-3181][MLLIB]: Add Robust Regression Algorithm with Huber Estimator

[fjiang6]

Huber Robust Regression including the test case and an example.
Passed the style checks

Jenkins, test this please.

Jenkins, add to whitelist.

@fjiang6 Could you try LBFGS instead of SGD?

The failed test is "org.apache.spark.graphx.lib.TriangleCountSuite.Count two triangles", which is a part I never touched. What could be the possible reason for this failure?

[ankurdave]

Jenkins, retest this please.

This was a problematic commit in GraphX which I just reverted, so a retest should fix the problem.

Can you please retest this? Thanks!

I think this contribution may have "timed out", along with #2110 . They're probably good implementations, but I am not clear if this will be taken forward to be part of Spark. In any event it doesn't merge and is not necessarily written for the new ML pipelines API. Does anyone else have an opinion on whether this should be closed out, or needs to be revived?

@fjiang6 in breeze we added ADMM based proximal minimizer and a proximal algorithm for Huber Loss...Could you please take a look at breeze.optimize.proximal.NonlinearMinimizer and Proximal.ProximalHuber and see if you can use NonlinearMinimizer ? Huber is as difficult as L1 (perhaps more difficult) since I have not seen a projection operator for Huber...For reference please follow Professor Boyd's paper on ADMM and Proximal Algorithms

The jar is available on 0.12-SNAPSHOTS
