Fixes OVS DPDK scenarios

This fixes nosdn OVS DPDK scenarios to work with OVS 2.6.  It also adds
support for the ODL DPDK scenario.  OVS DPDK configuration is done
during preconfig on compute nodes.  All nodes make use of first boot
script to get kernel params like hugepages.  The network settings are
modified to use real nic names for the virtual network settings file.
This is required due to a timing bug with os-net-config and using
first-boot script.  The network settings file also contains the UIO
driver to use with DPDK.
