Keystone stop using config refs
Keystone stop using config refs

 - Rather than using config refs, deployments should be using a tool
   such as chef or puppet to set the options correctly.

 - Config refs have a bug where you can only reference an option in
   the DEFAULT group, which limits the usefulness, and with this
   feature it's impossible to move any config options out of the
   DEFAULT group, luckily this has been ignored anyways since I think
   everyone realizes how broken it is.
