Support exposing single annotations/labels via env downward API #297

User Story

As a developer, I would like VirtualCluster to support exposing annotations/labels via env downward API.

Detailed Description For example:

containers:
  - env:
    - name: LABEL_KEY
      valueFrom:
        fieldRef:
          apiVersion: v1
          fieldPath: metadata.labels['label1']
    - name: ANNO_KEY
      valueFrom:
        fieldRef:
          apiVersion: v1
          fieldPath: metadata.annotations['anno1']

The fieldRef used for that will sync to the super cluster.

Anything else you would like to add:
