 |  :param etag: The string representing a ETag for the device twin, as per
 |   RFC7232.
 |  :type etag: str
 |  :param version: The version for the device twin including tags and desired
 |   properties
 |  :type version: long
 |  :param device_etag: The string representing a ETag for the device, as per
 |   RFC7232.
 |  :type device_etag: str
 |  :param status: The enabled status of the device. If disabled, the device
 |   cannot connect to the service. Possible values include: 'enabled',
 |   'disabled'
 |  :type status: str or ~protocol.models.enum
 |  :param status_reason: The reason for the current status of the device, if
 |   any.
 |  :type status_reason: str
 |  :param status_update_time: The date and time when the status of the device
 |   was last updated.
