Description
When building serviceEffectivePolicies -
populateReferencedKubernetesServices
logic is the heaviest part regarding CPU consumption. This logic is relevant only for egress policies (to work around AWS CNI limitation). Therefore, in this PR we changed it so it will only run if egress is enabled.
