Ability to run functional tests for magnum

[Davanum Srinivas (DIMS)]

Currently we just have unit tests. So we need to setup a devstack job in our CI to be able to stand up an actual magnum instance and run some of the command line utilities and a set of functional tests to ensure that we don't break any functionality as well.

    Make room for functional tests

    We need to consolidate the unit tests into a separate
    directory so we can run just the unit tests in our py27
    tox target. And we can in subsequent reviews add a parallel
    directory with functional tests.

    Convert to new DevStack plugin model for functional testing

    Switch over to the new plugin style as documented here:
    http://docs.openstack.org/developer/devstack/plugins.html

    Makes it very easy to setup a CI job. Added a new
    directory for functional job and the tests are run
    from the post_test_hook.sh. There's even a "magnum bay-list"
    in the shell script to show that we are actually making
    calls to the magnum API endpoint and things are working
    fine. Note that this is just the minimal plumbing needed
    and there's a lot more effort needed to come up with
    proper test cases for testing magnum functionality.
