fix azure disk creation issue when specifying external resource group

**What this PR does / why we need it**:
fix azure disk creation issue when specifying external resource group, after azure disk creation succeeded, it fails to get azure disk state since it's still using original resource group

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #65515

**Special notes for your reviewer**:
Together with https://github.com/kubernetes/kubernetes/pull/65443, this feature has been done, I will cherry-pick to prior versions later.
So in the end, we have two ways to make azure disk dynamic provision under an external resource group
 - specify `resourcegroup` parameter in azure disk storage class
```
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: hdd
provisioner: kubernetes.io/azure-disk
parameters:
  skuname: Standard_LRS
  kind: managed
  cachingmode: None
  resourcegroup: USER-SPECIFIED-RG
```

 - specify `volume.beta.kubernetes.io/resource-group` in PVC annotations
```
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-azuredisk
  annotations:
    volume.beta.kubernetes.io/resource-group: "USER-SPECIFIED-RG"  
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: hdd
```
**Release note**:

```
fix azure disk issue when specifying external resource group
```
