Improve messaging on volume expansion
- we now provide clear message to user what to do when cloudprovider resizing is finished
and file system resizing is needed.
- add a event when resizing is successful
- Use PATCH both in controller-manager and kubelet for updating PVC status
- Remove code duplication between controller-manager and kubelet for updating PVC status
- Only remove conditions that are managed by resize controller
```release-note
Improve messages user gets during and after volume resizing is done.

Volume metrics support for vSphere Cloud Provider
**What this PR does / why we need it**:
This PR adds Volume metrics support for vSphere Cloud Provider. With this we can monitor the available space, capacity and used space on volumes created using vSphere.
**Which issue(s) this PR fixes**
Fixes # https://github.com/kubernetes/kubernetes/issues/43527
Fixes # https://github.com/vmware/kubernetes/issues/208
**Special notes for your reviewer**:
Performed following steps to ensure metrics are reported correctly for vSphere Volumes.
- Created Dynamic PV using the PV claim of size 1Gi.
```

delete duplicate function for getting volume source
**What this PR does / why we need it**:
these two methods have same function.
```go

if spec.Volume != nil && spec.Volume.Glusterfs != nil {
return spec.Volume.Glusterfs, spec.Volume.Glusterfs.ReadOnly, nil
} else if spec.PersistentVolume != nil &&
spec.PersistentVolume.Spec.Glusterfs != nil {
return spec.PersistentVolume.Spec.Glusterfs, spec.ReadOnly, nil
}
return nil, false, fmt.Errorf("Spec does not reference a Glusterfs volume type")
}
func (plugin *glusterfsPlugin) getGlusterVolumeSource(spec *volume.Spec) (*v1.GlusterfsVolumeSource, bool) {
// Glusterfs volumes used directly in a pod have a ReadOnly flag set by the pod author.
// Glusterfs volumes used as a PersistentVolume gets the ReadOnly flag indirectly through the persistent-claim volume used to mount the PV
if spec.Volume != nil && spec.Volume.Glusterfs != nil {
return spec.Volume.Glusterfs, spec.Volume.Glusterfs.ReadOnly
}
return spec.PersistentVolume.Spec.Glusterfs, spec.ReadOnly

`getVolumeSource` seems to be much better.

The `devicePath` parameter is already validated in this [code](b7100f1ee7/pkg/volume/aws_ebs/attacher.go (L158)), so no need to check it again in the `for loop` as it won't be modified.

Use backup location to load cloud config for OpenStack
**What this PR does / why we need it**:
Since we are transitioning to external cloud provider, we need a way
to use the existing cinder volume plugin (from kubelet). With external
cloud manager kubelet will be run with --cloud=provider=external and
no --cloud-config file will be in the command line. So we need a way
to load the openstack config file from somewhere.
Taking a cue from kubeadm, which currently is picking up "/etc/kubernetes/cloud-config"
https://github.com/kubernetes/kubernetes/blob/master/cmd/kubeadm/app/phases/controlplane/manifests.go#L44
let's support the scenario where we fall back to this static location if
there is no cloud provider specified in the command line.
This has been tested with local-up-cluster using the following params:
EXTERNAL_CLOUD_PROVIDER=true
CLOUD_PROVIDER=openstack

Rework method of updating atomic-updated data volumes
**What this PR does / why we need it**:
This change affects the way that secret, configmap, downwardAPI and projected volumes (which all use the same underlying code) implement their data update functionality.
* Instead of creating a subdirectory hierarchy that will contain symlinks to each actual data file, create only symlinks to items in the root of the volume, whether they be files or directories.
* Rather than comparing the user-visible data directory to see if an update is needed, compare with the current version of the data directory.
* Fix data dir timestamp format year
* Create `..data` symlink even when a data volume has no data so consumers can have simplified update watch logic.

Fixed TearDown of NFS with root squash.
NFS plugin should not use `IsLikelyNotMountPoint()`, as it uses `lstat()` / `stat()` to determine if the NFS volume is still mounted - NFS server may use root_squash and kubelet may not be allowed to do `lstat()` / `stat()` there.
It must use slower `IsNotMountPoint()` instead, including in `TearDown()` function.
