Title:
  Instance fault's message shouldn't have exception class name

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  The instance fault['message'] is displaying exception class instead of
  actual exception message.

  Function add_instance_fault_from_exc in compute/utils.py have to be
  fixed to show detail (actual) message instead of exception class.

  def add_instance_fault_from_exc(context, conductor,
                                  instance, fault, exc_info=None):
      """Adds the specified fault to the database."""

      code = 500
      message = fault.__class__.__name__

      if hasattr(fault, "kwargs"):
          code = fault.kwargs.get('code', 500)
          # get the message from the exception that was thrown
          # if that does not exist, use the name of the exception class itself
          message = fault.kwargs.get('value', message)

      details = unicode(fault)
      if exc_info and code == 500:
          tb = exc_info[2]
          details += '\n' + ''.join(traceback.format_tb(tb))

      values = {
          'instance_uuid': instance['uuid'],
          'code': code,
          'message': unicode(message),
          'details': unicode(details),
          'host': CONF.host
      }
      conductor.instance_fault_create(context, values)
