+    Adds the following new fields that configure the Kubernetes Gloo Gateway pod :
+      - `kubeGateway.gatewayParameters.glooGateway.podTemplate.terminationGracePeriodSeconds` to specify the terminationGracePeriodSeconds.
+      - `kubeGateway.gatewayParameters.glooGateway.podTemplate.gracefulShutdown` to configure the graceful shutdown config for the envoy container.
+      - `kubeGateway.gatewayParameters.glooGateway.podTemplate.customLivenessProbe` to specify a custom liveness probe for the envoy container. No default liveness probe is set
+      - `kubeGateway.gatewayParameters.glooGateway.podTemplate.customReadinessProbe` to specify a custom readiness probe for the envoy container.
+      - `kubeGateway.gatewayParameters.glooGateway.podTemplate.probes` to enable the readiness probe. If the customReadinessProbe is not specified, a default readiness probe is set. No default liveness probe is set.
