Merge pull request #45182 from deads2k/tpr-08-simple-serving
Automatic merge from submit-queue (batch tested with PRs 45182, 45429) CustomResources in separate API server Builds on https://github.com/kubernetes/kubernetes/pull/45115. This adds a basic handler for custom resources. No status handling, no finalizers, no controllers, but basic CRUD runs to allow @enisoc and others to start considering migration. @kubernetes/sig-api-machinery-misc
