Comment 4 for bug 1961056

I tested in Train with NodeTLSCerts which appears to now be deprecated and removed. This previous CA injection happened in PreNetworkConfig which was before host_prep_steps and step1 . I moved this to step1 in master just to confirm if it works through this patch https://review.opendev.org/c/openstack/tripleo-heat-templates/+/829610 ...
