///
/// @RESTHEADER{GET /_api/job/{job-id}, Returns async job}
///
/// @RESTURLPARAMETERS
///
/// @RESTURLPARAM{job-id,string,required}
/// The async job id.
///
/// @RESTDESCRIPTION
/// Returns the processing status of the specified job. The processing status
/// can be
/// determined by peeking into the HTTP response code of the response.
///
/// @RESTRETURNCODES
///
/// @RESTRETURNCODE{200}
/// is returned if the job requested via job-id has been executed
/// and its result is ready to fetch.
///
/// @RESTRETURNCODE{204}
/// is returned if the job requested via job-id is still in the queue of pending
/// (or not yet finished) jobs.
///
/// @RESTRETURNCODE{404}
/// is returned if the job was not found or already deleted or fetched from the
/// job result list.
///
/// @EXAMPLES
///
/// Querying the status of a done job:
///
/// @EXAMPLE_ARANGOSH_RUN{JSF_job_getStatusById_01}
///   var url = "/_api/version";
///   var headers = {'x-arango-async' : 'store'};
///   var response = logCurlRequest('PUT', url, "", headers);
///
///   assert(response.code === 202);
///   logRawResponse(response);
///
///   var queryId = response.headers['x-arango-async-id'];
///   url = '/_api/job/' + queryId
///   var response = logCurlRequest('PUT', url, "");
///   assert(response.code === 200);
///   logJsonResponse(response);
/// @END_EXAMPLE_ARANGOSH_RUN
///
/// Querying the status of a pending job:
/// (we create a sleep job therefore...)
///
