the class TimelineReaderWebServices method getFlowRun.

/**
   * Return a single flow run for given UID which is a delimited string
   * containing clusterid, userid, flow name and flowrun id.
   *
   * @param req Servlet request.
   * @param res Servlet response.
   * @param uId a delimited string containing clusterid, userid, flow name and
   *     flowrun id which are extracted from UID and then used to query backend
   *     (Mandatory path param).
   * @param metricsToRetrieve If specified, defines which metrics to retrieve
   *     and send back in response.
   *
   * @return If successful, a HTTP 200(OK) response having a JSON representing a
   *     <cite>FlowRunEntity</cite> instance is returned. By default, all
   *     metrics for the flow run will be returned.<br>
   *     On failures,<br>
   *     If any problem occurs in parsing request or UID is incorrect,
   *     HTTP 400(Bad Request) is returned.<br>
   *     If flow run for the given flow run id cannot be found, HTTP 404
   *     (Not Found) is returned.<br>
   *     For all other errors while retrieving data, HTTP 500(Internal Server
   *     Error) is returned.

// since urls tend to get logged and anyone with access to
// the logs can extract tokens which are meant to be secret
