Long Running Queries Are Calculated Incorrectly

The long running query logic in DQPCore uses millisecs when comparing to the query threshhold which is in seconds. It should both be in seconds.

// check if only need long running queries.
long elapsedTime = System.currentTimeMillis() - req.getStartTime();
if (longRunningQueryThreshold == -1 || elapsedTime > longRunningQueryThreshold) {
results.add(req);
}
