                python-quantum-2013.2-0.3.b1.fc20.noarch requires python-quantumclient = 2:2.2.1-4.fc20

All of those have been renamed upstream and have been replaced with packages in Fedora with the new name 's/quantum/neutron' so openstack-quantum, python-quantum and python-quantumclient should all just be retired.
