fix issue with soft node affinity CRD

[georgebarbarosie]

This fixes the following error:

error: error validating "test-manifest.yaml": error validating data: ValidationError(postgresql.spec.nodeAffinity.preferredDuringSchedulingIgnoredDuringExecution[0]): missing required field "preference, weight" in do.zalan.acid.v1.postgresql.spec.nodeAffinity.preferredDuringSchedulingIgnoredDuringExecution; if you choose to ignore these errors, turn validation off with --validate=false

where test-manifest.yaml is:

apiVersion: "acid.zalan.do/v1"
kind: postgresql
metadata:
  name: test-manifest-cluster
  namespace: default
spec:
  teamId: "test"
  volume:
    size: 10Gi
  numberOfInstances: 1
  users:
    test: []
  databases:
    test: test
  nodeAffinity:
    preferredDuringSchedulingIgnoredDuringExecution:
    - weight: 1
      preference:
        matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values: [ helios ]
  postgresql:
    version: "12"
