Title:
  Azure datasource sometimes fails to find wireserver endpoint

Status in cloud-init:
  Expired

Bug description:
  The Azure datasource needs to communicate with the "Wireserver"
  control plane endpoint during provisioning. The IP address of the
  endpoint is passed to the VM as option 245 via DHCP. Code to retrieve
  that address is remarkably fragile across distros and in the face of
  changes users can make in choosing or configuring a network manager.
  When the datasource fails to find the endpoint address, provisioning
  will often fail, leaving an uncommunicative VM behind. While error
  messages are logged, the very nature of the problem (incorrect network
  setup and incomplete ssh key provisioning, among other things) means
  those log messages are difficult to access from outside the VM, and
  access to the VM itself (e.g. via ssh) is often blocked.
