[ovs-dev] [PATCH v7 12/13] dpdk-tests: Accept other configs in OVS_DPDK_START

As it stands, OVS_DPDK_START() won't allow other configs to be set
before starting the ovs-vswitchd daemon. This is a problem since some
configs, such as the "dpdk-multi-seg-mbufs=true" for enabling the
multi-segment mbufs, need to be set prior to start OvS.

To support other options, OVS_DPDK_START() has been modified to accept
extra configs in the form "$config_name=$config_value". It then uses
ovs-vsctl to set the configs.
