Open Stack

So I think everyone is in agreement that it should be option 2. I'm 
leaning towards this also but I'm wondering how much of this makes 
things easier for us as developers rather than operators.

How committed this are we in practice? For example, if we take 
nova.conf[0], if we follow option 2, theoretically all alternate 
hypervisor options (vmware/xen/nova-fake) etc. should come out and be 
left to override files. As should options templating options such as 
metadata_workers, listen ports, etc. globals.yml could probably be half 
the size it currently is. But if we go this route how many operators 
will stick with kolla? Maybe it won't be a big deal, the issue currently 
is the line is blurred on what gets templated and what doesn't.
