[James Slagle]

FYI, all rdo-manager installs are currently failing during the Undercloud
installation with:

Initial investigation indicates it's probably related to this Horizon packaging

https://review.gerrithub.io/#/c/230349/

It's look like that packaging change was included in the updated:
http://trunk.rdoproject.org/centos70/latest-RDO-trunk-CI/
