The `--parallel` flag to `test` is used as a binary "on" to mean "on all
cores." But it also tries to parse the value after it as a number. This is
annoying as there's no easy way to alias it as "on", since when adding a
test name afterwards it is parsed as an integer:
{{{
$ python manage.py test --parallel example.core.tests.test_a
usage: manage.py test [-h] [--noinput] [--failfast] ...
manage.py test: error: argument --parallel: invalid int value:
'example.core.tests.test_a'
}}}
Pytest's xdist plugin supports the value "auto" to mean "all cores." I
suggest we copy that.
