+++ This bug was initially created as a clone of Bug #1806406 +++ A number of improvements have been made to the upgrade tests in 4.5 that must be back ported to earlier releases: * Allow multiple sequential upgrades to be performed as a unit for 4.1-4.2-4.3-4.4 upgrade testing (https://github.com/openshift/origin/pull/24570) * Report router downtime (via the console and oauth routes) during upgrade like we do for the core platform and service load balancers (https://github.com/openshift/origin/pull/24580) * Ensure AWS service LB availability test is tuned consistently with GCP and Azure (https://github.com/openshift/origin/pull/24584) * Minor interspersed fixes to naming (https://github.com/openshift/origin/pull/24557) Backport all of these to 4.3 as one unit to avoid future cherry-picking issues. We need to go back to 4.3 to verify upgrade downtime as fixes are rolled out.
