I'm okay with this, but I'll let @cfarrend decide on the strategy he prefers for adopting gitlint across the repos.

ah, true, I forgot that part. If there is already a plan about applying gitlint across all repos, I am happy to close the PR.

@tachikoma-li I'm not sure if we already have a plan, but devops have been thinking about it, so they might be the best to advise on which approach will be easier to maintain in the future.

I guess I'll merge this one for now. We can revise it once dev has a better way to consistently manage this issue across repos. @leoadec
