--raw_output is nice, but it would be nicer if could show only output after KUnit tests ahve started.
So change the flag to allow specifying a string ('kunit'). Make it so `--raw_output` alone will default to `--raw_output=all` and have the same original behavior.
Drop the small kunit_parser.raw_output() function since it feels wrong to put it in "kunit_parser.py" when the point of it is to not parse anything.
E.g.
$ ./tools/testing/kunit/kunit.py run --raw_output=kunit ... [15:24:07] Starting KUnit Kernel ... TAP version 14 1..1 # Subtest: example 1..3 # example_simple_test: initializing ok 1 - example_simple_test # example_skip_test: initializing # example_skip_test: You should not see a line below. ok 2 - example_skip_test # SKIP this test should be skipped # example_mark_skipped_test: initializing # example_mark_skipped_test: You should see a line below. # example_mark_skipped_test: You should see this line. ok 3 - example_mark_skipped_test # SKIP this test should be skipped ok 1 - example [15:24:10] Elapsed time: 6.487s total, 0.001s configuring, 3.510s building, 0.000s running
