Extend ForResource to support unknown resources with client pool

File: pkg/client/informers/externalversions/generic.go:51

Currently ForResource() only handles hardcoded resource types via switch statement. Need to extend it to dynamically handle unknown/arbitrary resources using a client pool.

Current behavior:

• Only supports gameservers and gameserversets
• Returns error for unrecognized resources

Expected:

• Support arbitrary GroupVersionResources
• Use dynamic client pool for unknown types
