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
