I don't know abut the current CI, but judging by recent discussion that 
is about KDE migrating to gitlab; quick search shows gitlab does allow 
prohibiting a merge if CI failed¹

Note however, in my experience of contributing to diffrent project CI 
often fails for reasons absolutely irrelevant to code being tested 
(e.g. errors in a CI script), in this case prohibiting a merge may 
worsen the situation.
