Title:
  cloudstack and azure datasources broken when using netplan/systemd-
  networkd

Status in cloud-init:
  Fix Committed
Status in netplan:
  Invalid
Status in cloud-init package in Ubuntu:
  Fix Released
Status in nplan package in Ubuntu:

Status in systemd package in Ubuntu:

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.
