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.
