[pve-devel] [PATCH storage/manager v3] allow upload & import of qcow2 in the web UI

[Filip Schauer]

Tested the following scenarios:
* Uploading a qcow2 image via the Web UI works fine.
* Uploading a file that is not in the correct format fails with "Image
   is not in qcow2 format".
* Adding a qcow2 image to an existing VM via the Web UI works fine.
* Creating a VM with an imported qcow2 disk via the wizard works fine.

The minor "ugliness" that the storage selector resets when the "Import
Image" checkbox is toggled is not a big problem in my opinion.

Overall this looks fine.
