When building fork PRs, we have the ability to set the Trust level on the PR, but I'd like to be able to filter, by fork owner, which PRs we build.

Our use case is that we have a large repo that builds hundreds of PRs a day, and each PR can trigger up to 100 jobs. Jenkins is unable to scale with this many build agents attached to a single master, so we would like to have a master per team/developer. Having this filter would allow us to have multiple masters point to the same main repo, but only build a subset of the open PRs.
