lib/neutron service prefixes are neutron-* not q-*. We should install
those packages either way.
The patch moves files/*/neutron into files/*/neutron-common so that we
can correctly match */neutron against service specific dependency files
(f.e. */neutron-agent) and load the common packages if any neutron-*
service is present.
