Created https://github.com/openshift/openshift-ansible/pull/8404
Fix is available in openshift-ansible-3.7.49-1
Upgrade ocp v3.6 to v3.7 blocked by BZ#1585657 now.
BZ#1585657 should be fixed by PR https://github.com/openshift/openshift-ansible/pull/8547/ , so no longer blocking this. Verify this bug with openshift-ansible-3.7.55-1.git.14.cfcf401.el7.noarch. During 3.6 to 3.7 upgrade, when etcd redeploy-certificates.yml is called, it could backup etcd certs and generate new cert files correctly.
