// overrideDNS overrides a container's host config if the following conditions are
// true:
// 1. Task has an ENI associated with it
// 2. ENI has custom DNS IPs and search list associated with it
// This should only be done for the pause container as other containers inherit
// /etc/resolv.conf of this container (they share the network namespace)
