Fix improper controller-runtime cache configuration

When AppWrappers are enabled, it is not correct to configure
the controller-runtime cache with a filter that only allows
services, secrets, etc with the RayCluster label to be cached.
This breaks any AppWrapper that contains one of these resource kinds.
