[TEST] deploy KB with 3 replicas , distributed on 3 nodes.

• ref to: https://github.com/apecloud/kubeblocks/pull/7352

Case two cases:

1. upgrade KB from previous version to 0.8.3 --> upgrade success
2. install KB 083 with values specifying:
   • replicas
   • kb lables
   • kb affinity
   • dp lables (dp for dataprotection)
   • dp affinity installation success, and 3 KB replicas are distributed on 3 DIFFERNET nodes.

here is an example of values.yaml to test:

replicaCount: 3
image:
  tag: 0.8.3-beta.19
extraLables:
  app.kubernetes.io/component: "kubeblocks"
tolerations:
- key: kb-controller
  operator: Equal
  value: "true"
  effect: NoSchedule
affinity:
  nodeAffinity:
    preferredDuringSchedulingIgnoredDuringExecution:
    - weight: 100
      preference:
        matchExpressions:
        - key: kb-controller
          operator: In
          values:
          - "true"
  podAntiAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
    - labelSelector:
        matchLabels:
          app.kubernetes.io/instance: kubeblocks
          app.kubernetes.io/component: "kubeblocks"
      topologyKey: kubernetes.io/hostname
dataProtection:
  image:
    tag: 0.8.3-beta.19
  affinity:
    nodeAffinity:
      preferredDuringSchedulingIgnoredDuringExecution:
      - weight: 100
        preference:
          matchExpressions:
          - key: kb-controller
            operator: In
            values:
            - "true"
    podAntiAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
      - labelSelector:
          matchLabels:
            app.kubernetes.io/instance: kubeblocks
            app.kubernetes.io/component: "dataprotection"
        topologyKey: kubernetes.io/hostname
  extraLables:
    app.kubernetes.io/component: "dataprotection"

1. try INSTALL a new version ,with above mentioned values (to make sure all newly installed KB can be distributed)
2. upgrade without any new values (to make sure all previously installed versioin can be upgrade)
3. there is a typo extraLables in my prevous post, fixed as extraLabels.

Only 3 nodes, addon pod schedule failed: didn't match pod anti-affinity rules with kubeblocks https://github.com/apecloud/kubeblocks/issues/7426 After increasing nodes to more than 3, install and upgrade kubeblocks were successful.
