While Red Hat does generally recommend to always configure readinessProbes and livenessProbes for all application running on OpenShift Container Platform 4, the following OpenShift Service Mesh components are missing the livenessProbes.

• istiod
• istio-egressgateway
• istio-ingressgateway

Given that beside some historical reason, there appears to be no real blocker to implement them. Hence to comply with general kubernetes recommendation, it's requested to have them added and configured to make sure liveness of the respective pods is properly evaluated, reported and taken into consideration by the platform.
