[dts] [PATCH V1] tests/ip_pipeline:add case pipeline_with_traffic_management

[Mo, YufengX]

Hi, yao,bing

*. Your test case will fail when run with below command. It is caused by your hard code of dpdk directory.
   mv /root/dpdk /root/dpdk2
   ./dts -d /root/dpdk2 -t test_perf_pipeline_with_traffic_management
*. Your vm config step value is larger than range, range should be multiple of step. Your config has no sense.
