Title:
  Ironic: Driver should validate the node's properties

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The Ironic nova driver will look at the Ironic node to fetch the
  amount of CPUs, memory, disk etc... But it doesn't validate any of
  this properties making it fail horribly if the node is misconfigured.
  It should be more resilient to failures.
