Description of problem: This is a "clone" of https://bugzilla.redhat.com/show_bug.cgi?id=1461531 and https://bugzilla.redhat.com/show_bug.cgi?id=1451275 for osp11. We are hit by this bz https://bugzilla.redhat.com/show_bug.cgi?id=1458841, and while a patch at the yum level is expected, we will make a workaround for each osp release.
Verified with openstack-tripleo-heat-templates-6.2.0-3.el7ost.noarch RHOS-11-z1 on RHEL-7.3 updated to latest on RHEL-7.4
