When pushing changes to gerrit for requirements proposals there are cases where we want to ignore push errors. Specifically when gerrit is complaining because you are pushing the same commit or one with identical comments. We should just ignore these errors as it means the current reqs proposal is up to date. See https://review.openstack.org/Documentation/error-no-changes-made.html for more info. Change-Id: I5d7a1991449a80f570191eaad49dc3f9a0ff1a6a
