Hi team, AFAIK, we built k8s/yarn/mesos as resource manager; but I'd like to did some enhancement to them, e.g. integrate with Volcano <http://github.com/volcano-sh/volcano> in k8s. Is that possible to do that without fork the whole spark project? For example, enable customized resource manager with configuration, e.g. replace `org.apache.spark.deploy.k8s.submit.KubernetesClientApplication` with `MyK8SClient`, so I can only maintain the resource manager instead of the whole project.
