The cfg API is now available via the oslo-config library, so switch to it and remove the copied-and-pasted version. Add the 2013.1b4 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. Add dependency_links to setup.py so that oslo-config can be installed from the tarball URL specified in pip-requires. Remove the 'deps = pep8==1.3.3' from tox.ini as it means all the other deps get installed with easy_install which can't install oslo-config from the URL. Make tools/hacking.py include oslo in IMPORT_EXCEPTIONS like it already does for paste. It turns out imp.find_module() doesn't correct handle namespace packages. Retain dummy cfg.py file until keystoneclient middleware has been updated (I18c450174277c8e2d15ed93879da6cd92074c27a). Change-Id: I4815aeb8a9341a31a250e920157f15ee15cfc5bc

This script is used to clean up Glance images that are cached in the SR. By

Options:

--dry_run - Don't actually destroy the VDIs
|
|
--all_cached - Destroy all cached images instead of just unused cached

images.
