    removing httplib2 test dependency

    Once upon a time, the python-*client libraries were primarily built to
    use httplib2. They have subsequently shift to using requests and thus
    urllib3. The horizon test helpers code was maintaining a reference to
    httplib2 as it intercepted errant library calls that were not mocked.

    httplib2 is not actively maintained and OpenStack is moving to remove it
    as a dependency. See
    http://lists.openstack.org/pipermail/openstack-dev/2016-March/089225.html
    for more details.

    This patch removed the httplib2 dependency. Upon removing the
    dependency it exposed a missed update from httplib2 to urllib3. A
    function that was intended to catch unmocked calls was only listening
    for httplib2 connections. This patch updates that failsafe to work with
    urllib3. Upon doing so, it pointed out many, many missing mocks and in
    turn, many broken tests that appeared to work because of API call
    failures. This patch adds the missing mocks and fixes the broken tests.

    The new failsafe prints the stack trace when an outside connection is
    attempted. Additionally, to fix the fact that a missed mock used to
    allow tests to potentially pass, as documented by bug 1517704, a test
    failure is now forced on tests where a missing mock is detected.
