info output about what's being run should go to stderr

[Monty Taylor]

(py27)mordred@camelot:~/src/storyboard$ .tox/py27/bin/python .tox/py27/bin/testr list-tests -q
running=OS_STDOUT_CAPTURE=${OS_STDOUT_CAPTURE:-1} \
OS_STDERR_CAPTURE=${OS_STDERR_CAPTURE:-1} \
OS_TEST_TIMEOUT=${OS_TEST_TIMEOUT:-60} \
DJANGO_SETTINGS_MODULE=storyboard.settings \
${PYTHON:-python} -m subunit.run discover -t ./ ./ --list
storyboard.stories.tests.SimpleTest.test_basic_addition

All of the output goes to stdout, which makes doing | wc -l kinda hard.

Also, -q does not work suppress it.

So I think this is reasonable (its the pattern we followed in bzr and it worked very well there). We may well want to update list-tests to have a --subunit option too, which would suite your case better (since you want to do programmatic introspection).
