@pcreech here is the 4.14 config

@chris1984 release engineering doesn't use tool_belt at all anymore (since Foreman 3.10). AFAIK these days it's only for the release owner to do cherry picks.

@ekohl I was just tagging him since he was the release engineer to get it merged. You are right it's only used for cherry-picks now. I was getting a PR based on the branching docs:

Add tool_belt config for new release:
Create a new yaml file using the nightly Katello config as a template: [tool_belt configs](https://github.com/theforeman/tool_belt/tree/master/configs/katello)
Manually update the following sections:
releases: update to current release. Move the previous ‘current’ release to prior_releases below.
prior_releases: Remove the oldest prior_release (check with that release owner first to see if there’s a reason it should stay)
repos: Update branch names to current versions, including any new releases that need to happen
ignores: Delete all items from this list and start fresh (this will be used for cherry-picks later)
tags: update Katello version number in all values. Check the nightly config to see if any tags/repos need to be updated
