Title:
  DigitalOcean DS defines mutliple gateways via meta-data

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

Bug description:
  [Impact]
  The cloud-init datasource for DigitalOcean allows for multiple gateways on any NIC.

  On Ubuntu 16.04, this breaks networking.service. For 17.04 and later,
  Ubuntu _replaces_ the default gateway with the second gateway on
  'ifup' after reboot.

  DigitalOcean is looking at changing the meta-data, however, this will
  result in another version of the meta-data JSON.

  [Regression Potential]

  Low. This change is scope to DigitalOcean only. DigitalOcean has
  tested this Datasource exhaustively.

  [TEST Cases]
  - provision on DigitalOcean with a private IP
  - reboot
  - confirm that a single route exists in /etc/network/interfaces
