we need to revisit this PR after 4.18 release.
I have added the UI support and fixed a critical bug.
However , it still does not work. the issues are
(1) in DB/UI, the volume has new size (I set to 11GB), but on secondary
storage, it is still the old size (8GB in my testing)
```
# qemu-img info
/mnt/secstoragetmp/volumes/2/498/b10834c2-8b11-33a5-add9-a2cc68f7f148.qcow2
image:
/mnt/secstoragetmp/volumes/2/498/b10834c2-8b11-33a5-add9-a2cc68f7f148.qcow2
file format: qcow2
virtual size: 8 GiB (8589934592 bytes)
disk size: 1.65 GiB
cluster_size: 65536
Format specific information:
compat: 0.10
compression type: zlib
refcount bits: 16
```
(2) after attaching it to a vm, the volume is copied to primary storage.
however, the size is still not changed (=old size)
```
# qemu-img info
/mnt/657524e2-065b-3ca8-9e97-746b3c7d17db/2792282d-1e69-40a7-9072-206c7ff133f5

```
In short, volume is never resized (on KVM). I did not see any log to resize
the volume.
