Title:
  cloud-init and nplan do not parse and use OpenStack networking
  correctly with netmask

Status in cloud-init:
  Fix Committed
Status in cloud-init package in Ubuntu:
  Fix Released
Status in cloud-init source package in Xenial:
  Confirmed
Status in cloud-init source package in Yakkety:
  Confirmed
Status in cloud-init source package in Zesty:

Bug description:
  networking data josn has:

  "ip_address" : "104.130.20.155",
  "netmask" : "255.255.255.0"

  "ip_address" : "10.184.3.234",
  "netmask" : "255.255.240.0",

  that got rendered into nplan as:
   - 104.130.20.155/255.255.255.0
   - 10.184.3.234/255.255.240.0

  which it failed to parse

  Stderr: Error in network definition //etc/netplan/50-cloud-init.yaml
  line 32 column 12: invalid prefix length in address
  '104.130.20.155/255.255.255.0'

  
  I believe nplan is expecing CIDR notation of /24 or some such. I belive the current plan is to fix cloud-init to generate /24 cidr notation in the nplan renderer.

  This needs SRU into xenial.
