Note that because it is now a gerrit footer, it both appears in the same block
as the Change-Id footer (no blank line between them), and isn't guaranteed to be
above the Change-Id footer. This doesn't matter during "git cl upload", when
a Change-Id hasn't been allocated yet, but will show up during "git cl
description".
