Title:
  RequestedVRamTooHigh failures during server create will get needlessly
  rescheduled

Bug description:
  RequestedVRamTooHigh can be raised during server create from the
  libvirt driver if the flavor's max video ram is less than the
  hw_video_ram specified in the image, and because the compute manager
  isn't handling that specific exception, it will result in a
  RescheduledException to another compute host, but this is never going
  to work on another compute host so we should just handle it and abort
  the build, since it's user-error.

  Long-term, we should be validating this in the REST API instead of on
  the compute although not all virt drivers support the image property
  and flavor extra spec - currently only the libvirt driver does but
  there is also a patch to add support for it with the vmware driver:
