task connection authSecretRef namespace does not fallback to the namespace the task is in

[peterwillis]

I noticed that the namespace field on the authSecretRef is required, and if not set falls back to the default namespace. With a small amount of guidance I am happy to submit a PR that makes it fall back to using the namespace the task is in.

rufio/controller/kube.go

Line 19 in ce6d290

key := types.NamespacedName{Namespace: secretRef.Namespace, Name: secretRef.Name}

@peterwillis Thanks. Tweaking this would require populating the namespace before submitting to the resolveAuthSecretRef() func at both https://github.com/tinkerbell/rufio/blob/main/controller/machine.go#L112 and https://github.com/tinkerbell/rufio/blob/main/controller/task.go#L107.
