I have noticed this change ^ is going to consume a lot more CI jobs
and I'm not sure we want it.

That's something we could even do now if nobody is against, to save CI
resources.
So we would have puppet4 jobs voting from newton and beyond, but
puppet3 jobs only in periodic pipeline...

Moving forward is a good thing but we need to continue to test puppet3
for newton, otherwise the message is too rigid for our users imho.

I'll try to find a middleground between what we want without consuming
too much resources.
