Comment 19 for bug 1750884

Currently maas sends v1 config to cloud-init. cloud-init converts
that to netplan. MAAS could certainly change change to either
a.) improve the v1 config that it sends to put dns as per-interface
b.) send v2 config with dns per-interface.

I don't think there is reason to justify either of those at this time.

I do think that at some point MAAS network configuration will be
hindered and they'll end up wanting to describe dns more eloquently.
That time is not yet upon us.

Mathieu, you tell us how to indicate global dns in netplan configuration
and cloud-init will make sure it gets through to netplan correctly.
