Support for Prow Owners file

There's a similar standard to github CODEOWNERS, made by the prow team.
https://github.com/kubernetes/community/blob/master/contributors/guide/owners.md

It would be great if you could support this standard. It's being used by the kubernetes team and in JenkinsX, for example.
