Fix proposed to branch: master
Review: https://review.openstack.org/96892

[Jeremy Stanley (fungi)]

This error simply means that the host key for the Gerrit server at review.openstack.org was not recognized by the zuul user, and either it needs to be manually accepted or preinstalled through some means.

On our zuul server, we do it with http://git.openstack.org/cgit/openstack-infra/config/tree/modules/openstack_project/manifests/zuul_prod.pp#n65 but your local configuration needs may vary.
