  **Added** an opt-in feature when using istio-cni in ambient mode to create a Istio owned CNI config
  file which contains the contents of the primary CNI config file and the Istio CNI plugin. This
  opt-in feature is a solution to the issue of traffic bypassing the mesh on node restart when the
  istio cni deamonset is not ready, the Istio CNI plugin is not installed, or the plugin is not
  invoked to configure traffic redirection from pods their node ztunnels. This feature is enabled by
  setting cni.istioOwnedCNIConfig to true in the istio-cni Helm chart values. If no value is set for
  cni.istioOwnedCNIConfigFilename, the Istio owned CNI config file will be named 02-istio-cni.conflist.
  The istioOwnedCNIConfigFilename must have a higher lexicographical priority than the primary CNI.
  Ambient and chained CNI plugins must be enabled for this feature to work.
