    Fix functional tests and tox 2.0 errors

    With the recent update to tox 2.0.x, environment variables such as
    OS_AUTH_URL are not passed by default, resulting in tests errors
    mentionning Keystone authentication failures.

    This patch reads credentials from the 'functional_creds.conf' config
    file, like it is done in novaclient, glanceclient, manilaclient and
    soon in cinderclient.

    Reading credentials the old way (the environment) is still possible.

     neutronclient/tests/functional/test_clientlib.py
