The errors happened when run on nodes in different providers.
Looking at the build logs, I also notice that they fail for the
stable/rocky branch but succeeded for other branches of the same
repository. They're specifically erroring when trying to reach the
Gerrit server over SSH, the connection details for which are encoded
on the .gitreview file in each branch. This leads me to wonder
whether there's something about the fact that the stable/rocky
branch of tripleo-ipsec is still using the old review.openstack.org
hostname to push, and maybe we're not pre-seeding an appropriate
hostkey entry for that in the known_hosts file?
