[Openstack-operators] [openstack-dev] Upstream LTS Releases

Hi all - please note this conversation has been split variously across
-dev and -operators.

One small observation from the discussion so far is that it seems as
though there are two issues being discussed under the one banner:
1) maintain old releases for longer
2) do stable releases less frequently

It would be interesting to understand if the people who want longer
maintenance windows would be helped by #2.
