Consider keeping the CI diversity, not running Zuul's CI tests on the Testing Farm

[Miro Hrončok]

Hello CI folks!

Several times somebody asked me "Why there are two CI jobs in Fedora dist-git 
PRs, when the Zuul's rpm-test and the *Fedora CI - dist-git test* run the exact 
same tests?"

My answers so far was: "I don't know why it happened, but now it works as a 
nice backup plan. It is very common that one of them breaks [1]. When you see 
an unreadable infrastructure failure [2] at one of them, you have a pretty good 
chance tat the other one would still work."

With the idea to switch Zuul to the Testing Farm (rpm-tmt-test), this benefit 
would be lost. We would just have two CI tests runs where both of them have 
infrastructure failures at the same times (see for example [3]), both of them 
run on the same system, and both of them run the same tests.

Could you please consider not doing that, at least until the overall stability 
of the CI improves?

Thanks,
