In addition, this patch allows each user to see all session variables of
all other users. It seems to be dangerous. It would be better to allow a user
to see its own session's variables. I'll change it as I mentioned.

> Most databases provide a way to get information about active sessions (e.g.,
> pg_stat_activity in postgresql, processlist in mysql, v$session in oracle,
> and so on).
> But, tajo does not have such table yet.
> Implementing session virtual table would be helpful to monitoring and
> administration.
