Unit tests fail with requests<2.3.0

[Brant Knudson]

The keystoneclient unit tests are failing when using requests<2.3.0. The current requirement is has requests>=2.2.0,!=2.4.0, so this needs to be supported.

Two tests are failing:

- keystoneclient.tests.unit.v3.test_auth_saml2.AuthenticateviaADFSTests.test_end_to_end_workflow
- keystoneclient.tests.unit.v3.test_auth_saml2.AuthenticateviaADFSTests.test_check_valid_token_when_authenticated

They both fail in the same way:

...
   File "/opt/stack/python-keystoneclient/.tox/py27/local/lib/python2.7/site-packages/requests/cookies.py", line 128, in extract_cookies_to_jar
    jar.extract_cookies(res, req)
 AttributeError: 'list' object has no attribute 'extract_cookies'

This is one of the causes of stable/juno not being able to get updated requirements.

    Fix tests to work with requests<2.3

    The tests didn't pass with requests<2.3 because of the cookies
    monkey-patching.

    To test this, make sure the requests library in your tox venv is
    the right level:

     $ .tox/py27/bin/pip install -U "requests<2.3"

    Then run the tests.
