Katello-service functionality has moved to foreman-maintain. We can redirect katello-service there since it uses the same arguments. Katello-service is used pretty widely in documenation and scripts, I don't see a need to deprecate this just yet (we always can later). I aligned the issue with foreman 1.19(katello 3.8), so katello 3.7 will still have the original katello-service script.
