Fixes two bugs with the schema definitions:
- Adds resources that are a part of the baseSchema (but aren't k8s resources).
- Adds logic to handle resources which aren't in a prefered version, but
are still in some version.
Updates the schema definitions refresh method to use a new debounce
method. Adds a handler which refreshes the definitions every 2
seconds after adding a CRD and every 10 minutes by default.
