The oslotest library has a nice openstack testing integrated base class that can ensure we setup our base test case using the right logging fixtures, test timeouts, and output fixtures that better operate in the openstack ecosystem. This will also allow us to remove some of the functionality that we currently have in our base test case and replace it with the equivalent (or better) functionality that oslotest now provides.
