Feature description

When the cluster storage is getting increased in size, the user does not know the status of the storage. A specific scenario where this could be seen like a UX gap is when the corresponding workbench is stopped:

Steps:

1. create a workbench with a pv storage of size n Gib
2. wait until the workbench is Running
3. stop the workbench
4. edit the pv storage size from UI from n to m (m > n)
5. what's the status of the re-size process?
6. go back to Edit storage modal: the input box for the size can still be changed (ok) and user can even lower the requested size to n < z < m (Even though the UI says the size can only be increased)
7. go to OCP console and check the status of the corresponding PVC object: it reports that the risezing process is waiting for a pod (i.e., workbench) to start. We could trigger this and show in the UI
