Vanilla_Multi_Queue: Add vanilla ovs multi-queue functionality

Adds multi-queue for vanilla OVS using virtio-net.

TunTap ports will use multi_queue parameter when ports are
created/deleted if guest nic queues are enabled and
vswitch is ovs vanilla. Virtio net will now add guest nic
queues to qemu command line if appropriate.

Reworked multi-queue documentation to reflect these changes.

Adds vhost net thread affinitization which is recommended
when performing vanilla ovs multi-queue.

Guests will require ethtool if using l2fwd or linux bridge
as the loopback application when vanilla ovs multi-queue
is enabled.

Modified dpdk setting in vswitch conf to be better worded
for separation from vanilla ovs multi-queue.

Updated release and installation doc for new vloop image
that includes required ethtool utility.
