CLI: add Multiqueue params.
This patch implements the following new CLI parameters that can be used in the --test-params list. 1. guest_nic_queues, which overrides all GUEST_NIC_QUEUES values 2. guest_testpmd_txq, which overrides all GUEST_TESTPMD_TXQ 3. guest_testpmd_rxq, which overrides all GUEST_TESTPMD_RXQ 4. guest_testpmd_nb_cores, which overrides all GUEST_TESTPMD_NB_CORES values 5. guest_testpmd_cpu_mask, which overrides all GUEST_TESTPMD_CPU_MASK values 6. vswitch_dpdk_multi_queues, which overrides VSWITCH_DPDK_MULTI_QUEUES 7. guest_smp, which overrides all GUEST_SMP values 8. guest_core_binding, which overrides all GUEST_CORE_BINDING values When they are present in the CLI the corresponding settings from the configuration files will be overridden. As an example a usage can be: ./vsperf --test-params "guest_nic_queues=2;guest_testpmd_txq=1;\ guest_testpmd_rxq=1;guest_testpmd_nb_cores=1"... v2: rebase + rework to add other CLI params as suggested and update doc. v3: changes in 'testusage.rst' doc.
