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.

+Note: Option VSWITCHD_DPDK_ARGS is used for vswitchd, which supports --dpdk
+parameter. In recent vswitchd versions, option VSWITCHD_DPDK_CONFIG will be
+used to configure vswitchd via ovs-vsctl calls.
 
 With the --socket-mem argument set to use 1 hugepage on the specified sockets as
 seen above, the configuration will need 9 hugepages total to run all tests
