// Retrieves metadata for a Greengrass core device. IoT Greengrass relies on
// individual devices to send status updates to the Amazon Web Services Cloud. If
// the IoT Greengrass Core software isn't running on the device, or if device isn't
// connected to the Amazon Web Services Cloud, then the reported status of that
// device might not reflect its current status. The status timestamp indicates when
// the device status was last updated. Core devices send status updates at the
// following times:
//   - When the IoT Greengrass Core software starts
//   - When the core device receives a deployment from the Amazon Web Services
//     Cloud
//   - When the status of any component on the core device becomes BROKEN
//   - At a regular interval that you can configure (https://docs.aws.amazon.com/greengrass/v2/developerguide/greengrass-nucleus-component.html#greengrass-nucleus-component-configuration-fss)
//     , which defaults to 24 hours
//   - For IoT Greengrass Core v2.7.0, the core device sends status updates upon
//     local deployment and cloud deployment
