    Description

      During ingress-gateway pod startup, there are always unhealthy events appearing for a few seconds in the controlplane namespace.

      There should be a way to configure the initalDelaySeconds for gateways in servicemesh.

      [quicklab@upi-0 ~]$ oc get pods | grep -i ingress
      istio-ingressgateway-b5d4b99cc-c4wwk 1/1 Running 0 33s
      [quicklab@upi-0 ~]$

      [quicklab@upi-0 ~]$ oc delete pod istio-ingressgateway-b5d4b99cc-c4wwk
      pod "istio-ingressgateway-b5d4b99cc-c4wwk" deleted
      [quicklab@upi-0 ~]$

      [quicklab@upi-0 ~]$ oc get events | grep -i unhealthy | grep ingress
