[dts] [PATCH 3/4] read compile switch config and compile dpdk before test

[xu,huilong]

update list:
    1. read compile switch config file
    2. set run suite list on this test
    3. update compile switch or apple patch
    4. compile dpdk and back up dpdk
    5. furnish interface for change different dpdk compile switch compile result
