I would consider it a big step for tht repo, to include test specific
code in it. *Upstream CI specific code* even

I agree, we should be able to branch only the options and configuration,
not the entire process. Process is constantly changing and it would be
a pain to backport all this changes.

I don't understand why you consider this code duplication and don't
consider branching code duplication too.
With branches you're duplicating even if you don't see all the
duplicates at once. Consider that with this method it could be easier to
"backport" a scenario modification, since you can do everything with a
single commit.
I would prefer a different format tough
templates/$BRANCH/scenario-001.yaml
test-environments/$BRANCH/scenario-001.yaml

This doesn't scale well, we would have to be able to select which
scenario to run anyway


I have one last consideration to make.
With the transition to quickstart, we're effectively moving the process
part of tripleo-ci to another repo.
After the transition we could consider tripleo-ci more options and
configuration that process, and the we could start branching it, without
all the drawbacks we considered here.
