feat: wait tenant be green to do command

How to test:
Deploy tenant and

apiVersion: job.min.io/v1alpha1
kind: MinIOJob
metadata:
  name: minio-test-job
  namespace: default
spec:
  serviceAccountName: minio
  tenant:
    name: mytest-minio
    namespace: default
  commands:
    - name: create-minio
      op: make-bucket
      args:
        name: memes
      dependsOn: []

1. When tenant have gone (or ref a unknown tenant). MinIOJob should have a Error status.
2. When tenant have been green. Operator should print will do somthing next .
