As breaking upgrades whenever a service is disabled as bad, setting this urgent for 4.0.

To test:
1) Install grizzly packstack --allinone
2) chkconfig neutron-server-off
3.a) Set up havana repo and update neutron rpms
 or to quickly verify
3.b) grab the sed script from the spec file (which should match below) and run, ensuring that chkconfig neutron off is output for neutron-server instead of a line just saying 'neutron-server'

chkconfig --type sysv --list|grep ^quantum| \
      sed -re 's/[0-6]:off//g
               s/([0-6]):on\s*/\1/g
               s/quantum/neutron/g
               s/^([a-z0-9-]+)\s+$/chkconfig \1 off/
               s/^([a-z0-9-]+)\s+([0-6]+)/chkconfig --levels \2 \1 on/'
