Comment 8 for bug 1745597

Verification-done on xenial: nplan 0.32~16.04.5
Verification-done on artful: nplan 0.32~17.10.4

With the updated nplan; the mii-monitor-interval set in configuration is correctly applied to the device as expected, and is processed as milliseconds or seconds, as appropriate to the config:

676 --> 676
676ms --> 676
1s --> 1000

ubuntu@warm-sole:~$ cat /sys/class/net/bond0/bonding/miimon
1000
ubuntu@warm-sole:~$ cat /etc/netplan/50-cloud-init.yaml
