  To: dts; +Cc: Ling Wei

1.Add -a option to support tester and dut in same server.
2.Use pmd.start_testpmd() to replace session.send_expect()
  to start testpmd.
3.Move create dut ssh session from set_up to set_up_all
  to reduce the number of creation.
4.Add close dut session in tear_down_all to close session
  when suite execute over.
