Agreed on gate testing, I'm just not sure the general direction people 
would want. I've done cross n-1 and n and n-2 and such and jinja2 
templates start to have a bunch of if conditions to handle specific 
releases peculiarities.

As far as 2.0.x containers and 3.0.x containers, what version of 
openstack projects compose 2.0.x, is there a mapping of something like:

   - nova:
      branches_supported: [stable/newton]
   - glance:
      branches_supported: [stable/newton, stable/mitaka]

Or is it just assumed that the mapping is sorta known? Unsure quite how 
to correlate a given kolla release to what underlying projects it can 
build into images or deploy or manage (is this online somewhere, or do I 
just have to dig through the code) :-P
