Bug description:
In Ubuntu artful, cloud-init renders network configuration through netplan.
This means that there is no dhclient and thus no /var/lib/dhclient/*.leases.
Azure and CloudStack both are reading those leases file to get useful
information about the platform.
Specifically:
* Azure reads option-245 from the dhclient response to find the IP address
of the metadata service.
* CloudStack reads the 'dhcp-server-identifier' option in the dhclient
response to get the address of the virtual router (metadata service). [1]
In ubuntu this happens to be done with systemd-networkd, so cloud-init
can possibly probably interact over the dbus with systemd-networkd to
get information. However that is less than ideal, as ultimately
cloud-init should not need to know that it systemd-networkd is
involved. It should be hidden via netplan. So there should be an
interface to get current networking configuratoin information from
netplan including dhcp lease response info.
