When creating additionalEgress in namespace other than the Service Mesh Control-Plane namespace, the resources are correctly created and kept up-to-date. But when removing the additionalEgress in the SMCP custom resource or deleting SMCP custom resource the objects related to the additionalEgress are not removed/cleared (only when they are not in the SMCP namespace).

As does are properly managed by the SMCP it would be expected that they are removed once either the configuration is removed or the SMCP is deleted.

The additionalEgress in a specific namespace is created based on https://github.com/maistra/istio-operator/blob/maistra-2.1/docs/crd/maistra.io_ServiceMeshControlPlane_GatewaysConfig_v2.adoc#egressgatewayconfig definition.
