Title: RequestSpotInstances does not accept MonitoringEnabled

Using ec2 request_spot_instances with :monitoring_enabled => true results in AWS::EC2::Errors::UnknownParameter: The parameter MonitoringEnabled is not recognized

Using :monitoring => {:enabled => true} does work, but it requires an update in the api_config yml.
