Upgrade to Openshift Container Platform 4.3.8: ca-bundle.crt not found.

Issue

• If you are upgrading to this release from OpenShift Container Platform 4.2 or OpenShift Container Platform 4.3.3 or earlier, you must restart all Pods after the upgrade is complete.-This is because the service CA is automatically rotated as of OpenShift Container Platform 4.3.5. The service CA is rotated during the upgrade and a restart is required afterward to ensure that all services are using the new service CA before the previous service CA expires. After this one-time manual restart, subsequent upgrades and rotations will ensure restart before the service CA expires without requiring manual intervention.
