Title:
  Some non-supported actions in Ironic nova driver do not return errors
  to the user

Status in OpenStack Bare Metal Provisioning Service (Ironic):
  Confirmed
Status in OpenStack Compute (Nova):
  New

Bug description:
  While performing checking Nova API actions that I expected to fail
  when testing with the Ironic driver, I noticed in some cases a
  positive response is returned, but the action fails within the compute
  process when the action is attempted to be executed. When working with
  other drivers, I expect to see some time of immediate response from
  the initial request stating that the action isn't possible. The
  actions I've specifically verified this with are:

  - Pause
