    Limit exposure of network device types to the guest.
    
    Previously, the 'type' of the hypervisor network device, was exposed to
    the guest directly. That does not make sense, as
    a.) this leaks needless information into the guest
    b.) the guest cannot be reasonably expected to make decisions
        based on a type of link that is present underneath the
        virtual device that is presented to the guest.
    c.) guests then are forced to either continuously track these types
        or to assume that unknown type is "phy".
    
    This limits the exposure of types to a specific list. Any other
    type will be shown to the guest as 'phy'.

Bug description:
  === Begin SRU Template ===
  [Impact]
  When a config drive provides network_data.json on Azure OpenStack,
  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.
  === End SRU Template ===

  We have discovered an issue when booting Xenial instances on OpenStack
  environments (Liberty or newer) and Hyper-V compute nodes using config
  drive as metadata source.

  When applying the network_config.json, cloud-init fails with this error:
  http://paste.openstack.org/show/RvHZJqn48JBb0TO9QznL/

  The fix would be to add 'hyperv' as a link type here:
  /usr/lib/python3/dist-packages/cloudinit/sources/helpers/openstack.py, line 587
