The consensus in the nova meeting today, I think, was that we generally 
like the idea of the DictOpt with global oslo ssl as the default and 
then be able to configure that per-service if needed.

Does anyone want to put up a POC on how that would work to see how ugly 
and/or usable that would be?  I haven't dug into the DictOpt stuff yet 
and am kind of time-constrained at the moment.
