Title:
  cloud-init openstack.py code does not recognize network type 'tap'

Status in cloud-init:
  Fix Released
Status in cloud-init package in Ubuntu:
  Fix Released
Status in cloud-init source package in Xenial:
  Fix Released

Bug description:
  ==== Begin SRU Template ====
  [Impact]
  Certain versions and configurations of Openstack produce a config
  drive that has network devices described as 'type: tap'.  Previously
  cloud-init would require those to be 'type: ethernet' or other.

  The fix was to allow 'tap' to be considered a "physical" type from the
  guest VM's perspective.

  [Test Case]
   * Boot a VM in the reporters environment,
   * add proposed,
   * rm -Rf /var/lib/cloud /var/log/cloud-init*
   * reboot
   * verify working network and no WARN in /var/log/cloud-init.

  [Regression Potential]
  This is verified fixed for the user in yakkety, and the fix understood, so
  likely the fix will work in xenial.

  The regression potential would be if a network_config.json file actually
  tried to create 'tap' network interfaces and referred to them as
  type: tap.  This would consider those to be physical interfaces.
  However, 'tap' type would not have been understood previously.  And the
  bug in that case is in openstack for giving non-deterministic configuration.
  ==== End SRU Template ====
