[JENKINS-43958] Project based authorization for GitHub branch source plugin

We used the GitHub branch source plugin to automatically scan for repositories containing a Jenkinsfile. This works really well. However one of the missing features we run into is the fact that we can't specify permissions per new job (per repository) since we can only view the configuration and not save it.

We would like to keep using the project based authorization matrix and manually assign permissions for each newly detected GitHub repository.
