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.
For each testenv in tox.ini which overrides the base testenv deps list,
explicitly include {pip,test}-requires in the list so that oslo-config
doesn't fail to install later when easy_install attempts to install
the tarball when doing 'python setup.py install'.
Retain dummy cfg.py file until keystoneclient middleware has been
updated (I18c450174277c8e2d15ed93879da6cd92074c27a).
