Subject: dpdk: Support new way of DPDK configuration in ovs-vswitchd
Configuration of DPDK options in ovs-vswitchd has changed.
Previously used option --dpdk was deprecated and all DPDK
related options have to be configured through ovsdb via ovs-vsctl
calls. VSPERF was modified to detect and use correct version
of DPDK configuration. New configuration options should
be put into VSWITCHD_DPDK_CONFIG dictionary.
VSPERF classes specific to OVS were refactored.
