Presubmit

[AndrewKushnir]

@brandonroberts I've rebased this PR on top of the latest master and run g3 presubmit to verify everything looks good. Could you please have a quick look at the changes to make sure there are no unexpected changes after rebase and return "merge" label back if everything is ok? Thank you.
