failing tests are too verbose

[Devin Carlen]

When jenkins executes the unit tests when a branch is approved, if the tests fail, the output reported back to launchpad is far too verbose.

There is a setting in pip to make the download status more quiet and we should incorporate this setting in either tools/install_venv.py or run_tests.sh, whichever makes more sense

Sample output:

    Re-architects the OpenStack Dashboard for modularity and extensibility.

    Implements blueprint extensible-architecture.
    Implements blueprint improve-dev-documentation.
    Implements blueprint gettext-everywhere.
    Implements blueprint sphinx-docs.

    Complete re-architecture of the dashboard to transform it from a standalone django-openstack app to a Horizon framework for building dashboards. See the docs for more information.

    Incidentally fixes the following bugs:

    Fixes bug 845868 -- no PEP8 violations.
    Fixes bug 766096 -- the dashboard can now be installed at any arbitrary URL.
    Fixes bug 879111 -- tenant id is now controlled solely by the tenant switcher, not the url (which was disregarded anyway)
    Fixes bug 794754 -- output of venv installation is considerably reduced.

    Due to the scale and scope of this patch I recommend reviewing it on github: https://github.com/gabrielhurley/horizon/tree/extensible_architecture
