Comment 11 for bug 1926758

I reverted https://review.opendev.org/c/openstack/python-tripleoclient/+/789131 and things are back to normal for me:
(undercloud) [stack@undercloud-0 ~]$ openstack stack environment show overcloud -f yaml |grep Image:
  ContainerBarbicanApiImage: undercloud-0.ctlplane.bgp.ftw:8787/tripleomaster/openstack-barbican-api:current-tripleo
  ContainerCephDaemonImage: undercloud-0.ctlplane.bgp.ftw:8787/ceph-ci/daemon:v6.0.0-stable-6.0-pacific-centos-8-x86_64
  ContainerCinderApiImage: undercloud-0.ctlplane.bgp.ftw:8787/tripleomaster/openstack-cinder-api:current-tripleo

I.e. no more quay.io
