Title:
  Allow resize root_gb to 0 for volume-backed instances

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Currently, after an instance launched with bootable volume and flavor
  with non-zero disk. If we resize this instance to an flavor with zero
  disk, Nova API will throw exception.

  As for volume-backed instance, the root volume doesn't occupy any
  space in nova-compute node. So it should not be limited by flavor's
  root_gb.
