Bug description:
  === Begin SRU Template ===
  [Impact]
  When a config drive provides network_data.json on Openstack running on
  ESXi cloud-init will fail to configure networking.

  Console log and /var/log/cloud-init.log will show:
   ValueError: Unknown network_data link type: hyperv

  This woudl also occur when the type of the network device as declared
  to cloud-init was 'hw_veb', 'hyperv', or 'vhostuser'.

  [Test Case]
  Launch an instance with config drive on hyperv cloud.

  [Regression Potential]
  Low to none. cloud-init is relaxing requirements and will accept things
  now that it previously complained were invalid.

  This is very similar to change in bug 1642679.
  Upstream Openstack Merge proposal to stop this from continually
  happening at https://review.openstack.org/#/c/400883/
  === End SRU Template ===

  When booting an OpenStack instance, cloud-init fails with:
