Documentation for how to run tests is out of date

[Brad Pokorny]

The documentation for how to run tests for keystonemiddleware is out of date:

http://docs.openstack.org/developer/keystonemiddleware/

Running the tests with "python setup.py test" results in a bunch of errors:

ImportError: Failed to import test module: keystonemiddleware.tests.unit.test_s3_token_middleware

Running with tox currently gets them to pass on the master branch.

    Update documentation for running tests

    The documentation for how to run tests currently says to use
    "python setup.py test", which results in errors. Update the docs
    to specify tox.
