> Implement query history server.

> Key: TAJO-1014

> Project: Tajo
> Issue Type: Sub-task
> Components: tajo master
> Reporter: Jaehwa Jung
>
> Currently, TajoMaster maintains its query history in memory. In the result,
> if you shut down the master, you never can find your query history. In
> addition, if you shut down the active master on HA mode, you never can find
> the history on the backup master. Because the backup master can't access the
> active master query history. Thus we need to implement query history server
> which maintains its contents on shared storage like HDFS.
