The fields of the Device resource to be returned in the response. The
fields id and num_id are always returned, along with any
other fields specified in snake_case format, for example:
last_heartbeat_time.
The maximum number of devices to return in the response. If this value
is zero, the service will select a default size. A call may return fewer
objects than requested. A non-empty next_page_token in the response
indicates that more data is available.
The value returned by the last ListDevicesResponse; indicates
that this is a continuation of a prior ListDevices call and
the system should return the next page of data.
