1. update network-y stuff for supporting ubuntu/bionic as master …

   On bionic, we don't have eth0 hard coded. example below, so we use `ip
   route` to figure out the default ethernet interface
   ```
   dims@kubernetes-master:~$ ip link
   1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
       link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   2: ens4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1460 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
       link/ether 42:01:0a:80:00:23 brd ff:ff:ff:ff:ff:ff
   3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default
       link/ether 02:42:b2:4e:dd:86 brd ff:ff:ff:ff:ff:ff
   ```
   
   Also, bionic uses systemd-resolver by default and adds entries in
   /etc/resolv.conf that CoreDNS does not link. So follow the
   recommendation in the documentation to specify resolv.conf explicitly
