Yahoo Implementation of Istio CNI:
-----------------------------------

Yahoo didn't adopt the native method of running istio-cni-node Daemonset for the following reasons,
     1. There could be a chance of race condition that a POD can be launched without istio-proxy sidecar,
     when the istiocni DS pod is shutting down as it remove the istio cni chained plugin configuration
     from CNI config file(/etc/cni/net.d/10-ptp.conflist).
     2.  Daemonset ISTIO-CNI-NODE conflicted the on-perm implementation of CNI config file Management.
