Allow console clusterRef to reverence cluster in different namespace

[yvespp]

I want to deploy the console and the redpanda cluster in two different namespaces. Mainly to have the config separated and for easier network rule and policy configuration.

Could you add an optional namespace field to clusterRef to reference a cluster in a different namespace? For example:

apiVersion: cluster.redpanda.com/v1alpha2
kind: Console
metadata:
  name: console
spec:
  cluster:
    clusterRef:
      name: redpanda
      namespace: redpanda-cluster

In the code it looks like it always sets the namespace to the namespace of the console resource.
Not sure if there are security concerns or if the clusterRef mechanism would work if not in the same namespace.
