This is currently blocked by #6846. Once the issue is resolved I can easily clean up this PR for review.

@IgorMinar This is the PR blocked on #6846. Is there a way to rerun it on travis before submitting?

I'll rebase on top of @Mlaval's PR #5393 and see.

#6846 is fixed now so this PR should be unblocked

@yjbanov is this rebased or still failing on the latest?

This is failing with rebase on top of master after #6846 was submitted. I only gave it one attempt. Haven't looked at what's going on yet.

Replaced by: #7725
