If we do the GVO route, would folks be comfortable with Jenkins taking care
of promoting cherrypicks to a staging branch (say, 2.x-staging), and then
Jenkins, again, running the tests and pushing that through to gerrit/2.x?
(As always, the push to the official ASF repo is only done by a human,
using bin/push_to_asf.sh.)

Would folks be comfortable if I phased in GVO over the coming days?

Currently, GVO integration is tied up with Gerrit, and generating Gerrit
e-mails for things that we don't want to review seems spammy.

Thanks!
