fix incorrect error info when creating an azure file PVC failed
**What this PR does / why we need it**:
when creating an azure file PVC failed, it will always return following error which is totally incorrect:
```
Failed to provision volume with StorageClass "azurefile-premium": failed to find a matching storage account
```
The incorrect error info would mislead customer a lot, I would suggest return error directly if create first file share failed.
By this PR, the error info would be like following, which would provide user detailed and **correct** info:
```

Skip pods that refer to PVCs that are being deleted
**What this PR does / why we need it**:
New check was added to `Schedule()` to make sure that a scheduled pod refers to existing PVCs that are not being deleted.
In 1.9 we plan to add a new feature that uses finalizers on PVC to protect PVCs that are used by a running pod from being deleted. This finalizer will be removed when all pods that use a PVC are finished or deleted. See https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/postpone-pvc-deletion-if-used-in-a-pod.md for details.
I needed to pass `pvcLister` to `GenericScheduler`.
UX:

Make kubectl explain print the Kind and APIVersion of the resource
**What this PR does / why we need it**:
Kubectl explain currently doesn't print out the Kind and APIversion of the resource being explained. When running `kubectl explain hpa.spec`, for example, there is no way of knowing whether you're looking at the `autoscaling/v1` or the `autoscaling/v2beta1` version.
Also, `kubectl explain` is often used as a reference when writing YAML/JSON object manifests. It allows you to look up everything except the API version. Currently, you either need to know the API Version of a resource by heart or look it up in the online API docs.
This PR fixes both problems by having `kubectl explain` print out the full Kind and APIVersion of the resource it is explaining.
Here are a few examples of the new output:
```
$ kubectl explain deploy

$ kubectl explain hpa.spec

**Release note**:
