During #284 we set the ClusterScalingSchedule scope as `Cluster` but
just for kubebuilder. This flag has no effect in the generated clients.
It means the generated clients expect a namespace argument when handling
ClusterScalingSchedule resources. It works fine to list all of the
resources but makes it impossible to request a specific resource
defining its name.
This commit sets the `+genclient:nonNamespaced` flag for the CRD and
adds the regenerated clients. It does not affect any of the usage of the
clients in this codebase so far.
