Example for running individual unit tests doesn't work

[Ralf Haferkamp]

TESTING.rst in the neutron git repo has this examples for running individual unit tests:

  For example, the following would run only the JSONV2TestCase tests from
  neutron/tests/unit/test_api_v2.py::

        $ ./run_tests.sh neutron.tests.unit.test_api_v2:JSONV2TestCase

  or::

        $ ./tox neutron.tests.unit.test_api_v2:JSONV2TestCase

If I run this on my test system (openSUSE 13.1) it will not execute any test case:
====================================================
Running `OS_TEST_PATH=neutron/tests/unit tools/with_venv.sh python -m neutron.openstack.common.lockutils python setup.py testr --slowest --testr-args='--subunit neutron.tests.unit.test_api_v2:JSONV2TestCase'`
running testr
running=OS_STDOUT_CAPTURE=1 OS_STDERR_CAPTURE=1 OS_LOG_CAPTURE=1 ${PYTHON:-python} -m subunit.run discover -t ./ ${OS_TEST_PATH:-./neutron/tests/unit} --list
Slowest Tests

----------------------------------------------------------------------
Ran 0 tests in 7.737s

OK
====================================================

Simply replacing the ':' with a '.' works here.

    Fix example for running individual tests

    The ':' syntax doesn't seem to work anymore. Additionally fix the "tox" call to
    not try to run it from the current working directory. It's usually installed
    somewhere in $PATH.
