Distribute dpdk/vhostuser between CPUs for SA OVS
Update Yardstick with ability to distribute DPDK/vhost-user ports/queues between CPU cores. Extended OVS add vhost-user interface command with option "n_rxq", provided in the test case. Ordered ports added to OVS. JIRA: YARDSTICK-1490 Change-Id: I71f5d878a9ee3a11f636762fc16b04ee6bc79e14 Signed-off-by: Stepan Andrushko <stepanx.andrushko@intel.com>
