/assign sadasu

On cloud platforms, the CoreDNS Corefile's Upstreams were getting generated using the host's /etc/resolv.conf that is modified by network manager to include the local host. That resulted in the CoreDNS upstreams to include the IP of the node on which the CoreDNS static pod was running on. Fixed to use the NetworkManager's original upstream resolv.conf instead.
