> Set better default DStream checkpoint interval

> DStream checkpoint interval is by default set at max(10 second, batch
> interval). That's bad for large batch intervals where the checkpoint interval
> = batch interval, and RDDs get checkpointed every batch.
> This JIRA is to set the checkpoint interval of trackStateByKey to 10 * batch
> duration.
