functional test fails with RuntimeError: http_proxy or https_proxy set in environment, please unset

[Balazs Gibizer]

In an environment where http proxy is needed to create a python virtual env for the test run the functional tests fail with the similar stack traces:

    Traceback (most recent call last):
      File "nova/tests/functional/notification_sample_tests/test_instance.py", line 91, in setUp
        super(TestInstanceNotificationSample, self).setUp()

        'http_proxy or https_proxy set in environment, please unset')
    RuntimeError: http_proxy or https_proxy set in environment, please unset

This is because passenv config of tox.ini contains the http_proxy and https_proxy env variables and therefore tox passing them into the test executor.

As a side note. If build a virtualenv with the proxy set, then unset the proxy variables then star tox -e functional then I got a different failure:

    do not pass proxy env variables by tox

    In an environment where http_proxy env variable is needed to buil a
    proper python virtualenv the functional test fails with:
    RuntimeError: http_proxy or https_proxy set in environment, please unset

    This patch removes passing proxy env varibles in tox.ini to avoid this
    error.
