run_test.sh doesn't run individual tests

[Michael Kerrin]

When you try and run an individual test the testing framework will run your test and then immediately run all the unit tests despite you asking just to run on test.

This is very annoying when you are trying to develop something.

    Fix up the test framework

    When trying to test a bug the cinder test framework was
    running all the tests when I just wanted one to run.

    Instead of fixing this problem in nose I tried to move cinder to
    testr. I copied a fair bit of code from nova to get this to work.
    This way at least if some one makes an improvement to the nova
    test framework cinder can improve here also.

    Note that now all the tests a thread safe. Added a concurrency argument
    to run_tests.sh that defaults to 1. You can specify your own level then
    and take the risk of intermittent failures. Tell jenkins to use a
    concurrency level of 1 to avoid failing gate jobs.

    Note One of these tests is broken and I have disabled for now. There
    is a bug for this here: https://bugs.launchpad.net/cinder/+bug/1173266

    Note: cinder.api.openstack.FaultWrapper is deprecated and is causing
    a circular import when I try and import cinder.tests.test_wsgi. This
    is fixed by only importing the openstack.FaultWrapper during the
    __init__ phase of the wsgi middleware.
