stable/liberty unit tests broken - keystonemiddleware conf

[Eric Harney]

Running py27 tests on stable/liberty @41cea9c20 currently results in many tests failing like this:

cinder.tests.unit.api.contrib.test_quotas.QuotaSetsControllerTest.test_show
---------------------------------------------------------------------------

Captured traceback:
~~~~~~~~~~~~~~~~~~~
    Traceback (most recent call last):
      File "cinder/tests/unit/api/contrib/test_quotas.py", line 100, in setUp
        self.fixture = self.useFixture(config_fixture.Config(auth_token.CONF))
    AttributeError: 'module' object has no attribute 'CONF'

This is with keystonemiddleware==4.6.0

Capping keystonemiddleware to <3.0.0 seems to work around this problem. We need to either fix our tests or add a version cap.

Successful run with: keystonemiddleware==2.4.1

    always use pip constraints

    This flips the tox.ini to always use constraints installation for
    all targets. It drops the extra -constraints targets in the process.
    This makes it so there is no developer change required to operate in our
    new world order.
