Description of problem:
Image-upload hangs when using block-volume if the underlying storage had volumemode=block because the scratch pvc is created with volumemode=filesystem

How reproducible:

Everytime

Steps to Reproduce:
1. Setup either iscsi persistent storage or nfs dynamic provisioner 
2. Try to create image dv with --block-volume

Actual results:

Expected results:

For the scratch to use volumeMode: Block, to allow a different storage class to be used for the scratch or documented volumeMode: Block has to be undefined
