Add a variable RUN_IN_NETNS if the user wants to run all the selected tests in namespace in parallel. With this, we can save a lot of testing time. Note that some tests may not fit to run in namespace, e.g. net/drop_monitor_tests.sh, as the dwdump needs to be run in init ns. I also added another parameter -p to make all the logs reported separately instead of mixing them in the stdout or output.log. Nit: the NUM in run_one is not used, rename it to test_num.
