[SR-IOV] Add support for ACCELERATOR_DIRECT VNIC type

Browse Source 
Add support in SR-IOV mechanism driver for VNIC type
"accelerator-direct".

This VNIC type refers to any device that supports hardware
acceleration of any kind and is provided by Cyborg [1].

NOTE: "accelerator-direct-physical" is not supported yet.

Added support in SR-IOV agent for ``accelerator-direct`` VNIC
type. This type represents a port that supports any kind of
hardware acceleration and is provided by Cyborg
(https://wiki.openstack.org/wiki/Cyborg). `RFE: 1909100
<https://bugs.launchpad.net/neutron/+bug/1909100>`_.
``accelerator-direct-physical`` is still not supported.
