operand.namespace should be dropped

[marquiz]

What happened:

I create nfd CR:

kubectl apply -f - << EOF
apiVersion: nfd.kubernetes.io/v1
kind: NodeFeatureDiscovery
metadata:
  name: nfd-master-server
  namespace: operators
spec:
  operand:
    image: 'k8s.gcr.io/nfd/node-feature-discovery:v0.10.1'
    namespace: nfd
EOF

NFD get's deployed in operators namespace, as it should. The operand.namespace field has no effect (as it shouldn't as it shouldn't be allowed to "contaminate" arbitrary namespaces with NFD) and it should be dropped from the CRD.

What you expected to happen:

The operand.namespace parameter should not be accepted at al.

How to reproduce it (as minimally and precisely as possible):

See above.

Anything else we need to know?:
