On the design, as we aim for role isolation, this should not reference the other roles variables. The right place would be something like vars/defaults.yml like you have in the PR.

Something similar to this is how I envision we should autoconfigure (at least) PostgrSQL tuning.
All the numbers derive only from one variable:
foreman_puma_threads_max, which (right now) would be the only one to "play" with.This approach tries to come up with similar figures to what current
--tuningwould return for the same hardware.
