Description
Enables upstream Istio 1.29.1 NetworkPolicies for all Istio components.
NetworkPolicies added
istiod (istio-system)
istio-cni (istio-system)
ztunnel (istio-system)
admin-ingressgateway (istio-admin-gateway)
tenant-ingressgateway (istio-tenant-gateway)
passthrough-ingressgateway (istio-passthrough-gateway)
egressgateway (istio-egress-gateway)
Note: Ambient Egress does not use the upstream helm chart, so not adding a netpol for that (the Authorization Policies created by the operator already lock down).
