The cfg API is now available via the oslo-config library, so switch to it and remove the copied-and-pasted version. Add the 2013.1b3 tarball to tools/pip-requires - this will be changed to 'oslo-config>=2013.1' when oslo-config is published to pypi. This will happen in time for grizzly final. Remove the 'deps = pep8' from tox.ini as it means all the other deps get installed with easy_install which can't install oslo-config from the URL. Retain dummy cfg.py file until keystoneclient middleware has been updated (I18c450174277c8e2d15ed93879da6cd92074c27a). Change-Id: I4815aeb8a9341a31a250e920157f15ee15cfc5bc
