Jan Gutter 4d32b45c15 Add support for vrouter HW datapath offloads
Add plumbing for Contrail/Tungsten Fabric datapath offloads

* This change expands the VNIC type support for the vrouter VIF type by
  adding 'direct' and 'virtio-forwarder' plugging support.

* After this change, the vrouter VIF type will support the following modes:
  * 'normal': the 'classic' tap-style VNIC plugged into the instance,
  * 'direct': a PCI Virtual Function is passed through to the instance,
  * 'virtio-forwarder': a PCI Virtual Function is proxied to the
    instance via a vhost-user virtio forwarder.

* The os-vif conversion function was extended to support the two new
  plugging modes.

* Unit tests were added for the os-vif conversion functions.

* OpenContrail / Tungsten Fabric is planning to consume this
  functionality for the 5.1 release.

* os-vif 1.14.0 is required to pass the metadata

This release adds support for ``direct`` and ``virtio-forwarder`` VNIC
types to the ``vrouter`` VIF type. In order to use these VNIC types,
support is required from the version of OpenContrail, Contrail or Tungsten
Fabric that is installed, as well the required hardware. At this time, the
reference os-vif plugin is hosted on OpenContrail at
https://github.com/Juniper/contrail-nova-vif-driver but is expected to
transition to Tungsten Fabric in the future. Version 5.1 or later of the
plugin is required to use these new VNIC types. Consult the `Tungsten
Fabric documentation <https://tungstenfabric.github.io/website/>`_ for
release notes, when available, about hardware support. For commercial
support, consult the release notes from a downstream vendor.
