CSIT-661: re-add vring256 tuned CFS for vpp workers and guest-testpmd

1. add vhost tests (L2XBD, L2XC and IP4BASE) with vring set to 256 and
   tuned CFS setting
2. add vhost tests (L2XBD, L2XC and IP4BASE) with vring set to 256 and
   default CFS setting

+| ... | with single links between nodes.
+| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-
+| ... | domain and MAC learning enabled. Qemu Guest is connected to VPP via
+| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting
+| ... | vhost-user interfaces using 5 cores pinned to cpus 5-9 and 2048M
+| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores
+| ... | (1 main core and 4 cores dedicated for io), forwarding mode is set to
+| ... | io, rxd/txd=1024, burst=64. DUT1, DUT2 are tested with 2p10GE NIC X520
+| ... | Niantic by Intel.
+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
+| ... | of packets transmitted. NDR and PDR are discovered for different
+| ... | Ethernet L2 frame sizes using either binary search or linear search
+| ... | algorithms with configured starting rate and final step that determines
+| ... | throughput measurement resolution. Test packets are generated by TG on
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
+| ... | (flow-group per direction, 253 flows per flow-group) with all packets
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
+| ... | payload. MAC addresses are matching MAC addresses of the TG node
+| ... | interfaces.
+| ... | *[Ref] Applicable standard specifications:* RFC2544.
